Coronary angiography is the gold-standard test for identifying blockages in the heart arteries — the investigation that gives your cardiologist or cardiac surgeon the road map they need to plan the right treatment. If you have been referred for coronary angiography, or if you already have an angiography report and want to understand what it means, Dr. Ved Prakash, Director of CTVS at Yatharth Super Speciality Hospitals, Greater Noida, explains everything clearly.   What Is Coronary Angiography? Coronary angiography is a catheter-based procedure that injects a special dye (contrast agent) directly into the coronary arteries while X-ray images are taken continuously. The dye makes the inside of the arteries visible on X-ray — revealing exactly where blockages are, how severe they are, and how many arteries are affected. Coronary angiography is performed in a cardiac catheterisation laboratory (cath lab), takes approximately 30–45 minutes, and is done under local anaesthesia — you are awake throughout. The catheter is most commonly inserted through the radial artery at the wrist (radial access) — which causes much less discomfort and allows you to go home the same day or the following morning. Why Is Coronary Angiography Recommended? Your cardiologist recommends coronary angiography when: You have chest pain on exertion that suggests angina An ECG, stress test (TMT), or echocardiogram shows changes suggesting blocked arteries You are being evaluated before major non-cardiac surgery (e.g., valve surgery) and are over 50 or have risk factors You have had a heart attack and require urgent assessment of the blocked artery CT coronary angiography has shown suspected significant blockages that need catheter-based confirmation What Happens During Coronary Angiography — Step by Step Preparation: You fast for 4–6 hours before the procedure. A thin tube (IV line) is placed in your arm. The access site (wrist or groin) is cleaned and numbed with local anaesthetic. Catheter insertion: A thin flexible tube (catheter) is inserted into the artery and guided up to the heart — guided by X-ray imaging. You feel pressure but no pain. Dye injection: Contrast dye is injected into each coronary artery. You briefly feel a warm flush through the chest — this lasts 10–15 seconds and is completely normal. Images recorded: X-ray images (cine-angiograms) are taken from multiple angles as the dye flows through the arteries — revealing any narrowings or blockages. Catheter removal: The catheter is removed and pressure applied to the access site. With radial (wrist) access, a compression band is placed and you can sit up and eat within an hour. How to Read Your Coronary Angiography Report This is the section no competitor explains — yet it is what every patient needs to understand. Percentage Blockage (Stenosis) 0–49% stenosis: Mild narrowing — does not significantly restrict blood flow. No intervention needed. Managed with medication and lifestyle changes. 50–69% stenosis: Moderate narrowing — may or may not be causing symptoms. Sometimes assessed further with an FFR (Fractional Flow Reserve) pressure wire to determine if it is truly restricting flow. 70–90% stenosis: Significant blockage — restricts blood flow. Almost always treated with angioplasty (stent) or included in a bypass surgery plan. 90–99% stenosis: Critical blockage — very high risk of heart attack. Urgent treatment required. 100% (total occlusion): Complete blockage — the artery is fully closed. Treatment depends on how long it has been blocked and whether viable heart muscle is at risk. Which Arteries Are Named in the Report LAD (Left Anterior Descending): Supplies the front of the heart — the most important coronary artery, also called the “widow maker” LCx (Left Circumflex): Supplies the side and back of the heart RCA (Right Coronary Artery): Supplies the right ventricle and back of the left ventricle Left Main: The trunk from which the LAD and LCx branch — a critical vessel; significant blockage here is a cardiac emergency What Happens After Coronary Angiography If a Blockage Is Found? Single, simple blockage in a non-diabetic patient: May be treated with angioplasty (stenting) immediately in the same session or scheduled shortly after Multiple blockages or complex anatomy: The coronary angiography images are reviewed by a Heart Team — cardiologist and cardiac surgeon — to decide between angioplasty and bypass surgery based on the SYNTAX score Left main disease: A cardiac surgery review is mandatory — bypass surgery is usually preferred No significant blockages: The angiography rules out coronary artery disease — your chest symptoms need evaluation for other causes If you have had coronary angiography and have been told surgery is needed, a cardiac second opinion in Delhi NCR from Dr. Ved Prakash gives you a complete, independent review of your angiogram images and a clear treatment recommendation.

Coronary angiography is a catheter-based diagnostic procedure using dye and X-ray to reveal coronary artery blockages. It is extremely safe — the risk of serious complication is less than 0.1% in elective cases. It is performed under local anaesthesia and takes 30–45 minutes. What does 70% blockage on angiography mean? A 70% stenosis means the artery is narrowed to 30% of its normal diameter — significantly restricting blood flow. Most cardiologists and cardiac surgeons recommend treatment (angioplasty or bypass, depending on location) for blockages of 70% or more in major coronary arteries. Is coronary angiography painful? Not painful. The access site is numbed with local anaesthetic. Patients feel brief pressure when the catheter is moved, and a warm flush when the dye is injected — both normal and temporary. Most patients find coronary angiography significantly less uncomfortable than anticipated. What happens after coronary angiography if a blockage is found? A single simple blockage may be stented in the same session. Multiple or complex blockages are reviewed by a Heart Team who recommend angioplasty or bypass surgery based on the SYNTAX score and patient factors.

An echocardiogram is an ultrasound scan of your heart — the single most important investigation in cardiac medicine, and the test that Dr. Ved Prakash reviews before making any treatment decision. If your doctor has ordered an echocardiogram, this article explains what it is, how to read the key results, and what the findings may mean for your treatment at Yatharth Super Speciality Hospitals, Greater Noida.   What Is an Echocardiogram — The Basics An echocardiogram — often called an “echo” — uses high-frequency sound waves (ultrasound) to produce real-time, moving images of your heart. Unlike an ECG (which records electrical signals), an echocardiogram shows the actual structure and movement of the heart: the walls, chambers, and valves — all in motion, in real time. A standard echocardiogram takes 20–30 minutes, involves no radiation, no pain, and no preparation. A gel is applied to the chest, and a transducer (probe) is placed on the skin to capture images. An echocardiogram is completely safe for all ages including children and pregnant women. What Does an Echocardiogram Show? An echocardiogram provides information that no other test gives in one investigation: Ejection fraction (EF): The percentage of blood the heart pumps out with each beat — the most important measure of heart muscle function Regional wall motion: Whether each section of the heart wall is moving normally — areas that are not moving indicate old heart attack damage or current ischaemia Valve function: Whether each of the four valves is opening fully (stenosis) or closing completely (regurgitation), and the severity if abnormal Chamber size: Whether the heart chambers are enlarged — from chronic valve disease, high blood pressure, or cardiomyopathy Pericardial effusion: Fluid around the heart — which can compress cardiac function if significant Congenital defects: Holes (ASD, VSD) or other structural abnormalities in children and adults How to Read Your Echocardiogram Report — Key Numbers Explained Ejection Fraction (EF) This is the most important number on an echocardiogram report. It measures the pumping power of the left ventricle. 55–70%: Normal 40–54%: Mildly reduced — warrants medication review and repeat echocardiogram 30–39%: Moderately reduced — significant heart failure; treatment and close monitoring required Below 30%: Severely reduced — requires specialist cardiac care and may change surgical timing and technique Valve Grade (Severity) Each valve abnormality is graded on the echocardiogram as mild, moderate, or severe. Mild disease is monitored. Moderate disease is reviewed every 6–12 months. Severe disease — particularly with symptoms or evidence of chamber enlargement — typically requires surgical discussion. Wall Motion Score Each segment of the left ventricular wall is graded from 1 (normal movement) to 4 (bulging paradoxically — indicating an aneurysm). Any score above 1 in multiple segments indicates past heart attack damage or ongoing ischaemia from blocked arteries. Types of Echocardiogram Transthoracic echocardiogram (TTE): The standard echocardiogram — probe on the chest. Painless, no preparation, 20–30 minutes. Transoesophageal echocardiogram (TOE/TEE): A probe is passed into the oesophagus for much clearer images of certain structures — particularly the mitral valve and for detecting clots. Performed under sedation. Used before valve surgery and in suspected endocarditis. Stress echocardiogram: Echocardiogram performed during or immediately after exercise — reveals wall motion abnormalities that only appear when the heart is working hard. Used to detect blocked arteries when resting echocardiogram is normal. 3D echocardiogram: Three-dimensional reconstruction of the valve structure — increasingly used for surgical planning before mitral and tricuspid valve repair. When Does an Echocardiogram Lead to Further Treatment? An echocardiogram finding that typically leads to surgical consultation includes: Ejection fraction below 35% with symptoms of heart failure Severe aortic stenosis — particularly with symptoms Severe mitral regurgitation with increasing left ventricular dimensions Significant ASD or VSD with right heart enlargement Regional wall motion abnormality in a patient with symptoms — suggesting active ischaemia needing angiography Dr. Ved Prakash reviews every echocardiogram in full before any cardiac surgical recommendation — not just the summary. Book a consultation for heart valve surgery in Delhi NCR or arrange an online cardiac consultation and share your echo report via WhatsApp. Frequently Asked Questions — What Is an Echocardiogram What is an echocardiogram and is it the same as an ECG? No — an echocardiogram uses ultrasound to show the heart’s structure and movement. An ECG records only electrical signals. An echocardiogram gives vastly more information about valves, chamber size, and pumping function — it takes 20–30 minutes vs 5 minutes for an ECG. What does a normal echocardiogram report show? Normal echocardiogram findings: ejection fraction 55–70%, all four valves functioning normally, no wall motion abnormalities, normal chamber sizes, no fluid around the heart (no pericardial effusion). What does ejection fraction mean on an echocardiogram? Ejection fraction is the percentage of blood the left ventricle pumps out per beat. Normal is 55–70%. Below 40% indicates significant heart failure and influences decisions about surgery type and timing. Is an echocardiogram safe? Completely safe. An echocardiogram uses ultrasound, not radiation. No pain, no needles, no preparation for a standard study. Safe for children, pregnant women, and the elderly.

On-pump vs off-pump bypass surgery is one of the most specific questions patients ask before CABG — and it is a genuinely important one, because the right technique depends directly on your individual health profile. Dr. Ved Prakash, Director of CTVS at Yatharth Super Speciality Hospitals, Greater Noida, has extensive experience with both techniques and explains how the on-pump vs off-pump bypass surgery decision is made — and what it means for your recovery.   What Is On-Pump Bypass Surgery? In on-pump bypass surgery, the heart is temporarily stopped using a special medication (cardioplegia solution), and a heart-lung machine (cardiopulmonary bypass machine) takes over the job of circulating and oxygenating the blood while the surgeon operates. Because the heart is completely still, the surgeon can work with great precision in placing the bypass grafts. On-pump bypass surgery is the standard, time-tested technique that has been performed since the 1960s. It remains the default approach for most complex CABG operations worldwide — and it delivers excellent, consistent outcomes. What Is Off-Pump Bypass Surgery (OPCAB)? In off-pump bypass surgery — also called OPCAB or beating-heart bypass — the bypass grafts are attached while the heart continues to beat. No heart-lung machine is used. The surgeon uses mechanical stabilisers to gently immobilise a small area around the target coronary artery while the rest of the heart beats normally. Off-pump bypass surgery is technically more demanding — it requires greater surgical skill and experience than the standard on-pump technique. But in the right patients and the right hands, it offers meaningful advantages. On-Pump vs Off-Pump Bypass Surgery — Key Differences Feature On-Pump CABG Off-Pump CABG (OPCAB) Heart-lung machine used? Yes No Heart stopped during surgery? Yes No — heart continues to beat Surgical complexity Standard Higher — requires specialised technique Kidney complication risk Slightly higher Reduced in pre-existing kidney disease Stroke risk Slightly higher in aortic calcification Potentially lower in high-risk patients Blood transfusion need Slightly higher Often lower Graft completeness Easier to achieve all targets Some posterior targets technically harder Overall outcome Excellent Equivalent in experienced hands Who Benefits Most From Off-Pump Bypass Surgery? On-pump vs off-pump bypass surgery — the off-pump technique has specific advantages for certain patient groups: Patients with chronic kidney disease (CKD): The heart-lung machine can reduce kidney blood flow during surgery — off-pump bypass avoids this and is strongly preferred when baseline kidney function is already reduced Patients with a heavily calcified aorta: Clamping the aorta for the heart-lung machine in a calcified vessel can dislodge calcium fragments and cause stroke — off-pump surgery avoids aortic clamping in selected techniques Patients with significant lung disease (COPD): The heart-lung machine can worsen lung inflammation; off-pump bypass reduces this risk Elderly patients: Reduced exposure to the inflammatory effects of cardiopulmonary bypass may benefit older patients Jehovah’s Witnesses or patients refusing blood transfusion: Off-pump bypass surgery typically results in less blood loss Who Is Better Suited to On-Pump Bypass Surgery? In the on-pump vs off-pump bypass surgery comparison, on-pump is preferred when: The coronary arteries to be bypassed are in technically difficult positions (particularly posterior vessels on the back of the heart) that are harder to stabilise in a beating heart The heart is already significantly enlarged or weak — making stabilisation for off-pump technically challenging The operation needs to be combined with another procedure simultaneously (e.g., valve repair or aortic surgery) The surgeon’s experience is primarily with the on-pump technique — surgeon experience matters more than technique choice   The Most Important Factor — Surgeon Experience The on-pump vs off-pump bypass surgery debate in the medical literature largely resolves to one conclusion: in experienced hands, both techniques deliver equivalent long-term graft patency and mortality rates. The difference is in short-term kidney and neurological complication rates — which benefit specific patient subgroups with off-pump surgery. What this means practically: the technique that is safer for you is the one your surgeon has the most experience with, applied to your specific anatomy and health profile. Dr. Ved Prakash discusses this choice openly with every patient before surgery. Frequently Asked Questions — On-Pump vs Off-Pump Bypass Surgery What is the difference between on-pump and off-pump bypass surgery? In on-pump bypass surgery, a heart-lung machine temporarily takes over the heart’s function while the surgeon operates on a still heart. In off-pump bypass surgery, the grafts are attached while the heart continues to beat — no heart-lung machine is used. Both produce excellent outcomes in the right patient. Is off-pump bypass surgery safer than on-pump? Off-pump bypass surgery reduces kidney complication risk and may lower stroke risk in high-risk patients. However, it is technically more demanding and requires greater surgical experience. In experienced hands, both techniques deliver equivalent overall outcomes for most patients. Who is off-pump bypass surgery best for? Patients with pre-existing kidney disease, heavily calcified aortas, significant lung disease, or those at elevated risk of neurological complications from the heart-lung machine benefit most from off-pump bypass surgery. Can all blockages be bypassed in off-pump surgery? Most coronary artery blockages can be bypassed off-pump by an experienced surgeon. However, certain anatomical locations — particularly vessels on the back of the heart — are more challenging. If complete revascularisation cannot be achieved off-pump, conversion to on-pump surgery is performed without any compromise to safety.

The bypass surgery vs angioplasty decision is the most important — and most frequently misunderstood — choice in cardiac treatment. Both procedures treat blocked coronary arteries. Both save lives. But choosing the wrong one for your anatomy can mean going back for another procedure in 5 years — or worse. Dr. Ved Prakash, Director of CTVS at Yatharth Super Speciality Hospitals, Greater Noida, explains exactly how bypass surgery vs angioplasty is evaluated — and what determines the right answer for each patient.   Bypass Surgery vs Angioplasty — What Each Procedure Does Before comparing bypass surgery vs angioplasty, the basic mechanism of each must be clear. Angioplasty (PCI / stenting): A thin catheter is inserted through the wrist or groin artery and guided to the blockage. A balloon inflates to widen the artery, and a metal mesh tube (stent) is left in place to keep it open. No chest incision. Recovery in 1–3 days. Best for: a single blockage or a simple two-vessel disease in a non-diabetic patient. Bypass surgery (CABG): A healthy blood vessel is taken from the chest wall or leg and sewn in to bypass the blocked section entirely — creating a permanent new route for blood. Requires a chest incision and 7–10 days in hospital. Best for: multiple blockages, left main disease, diabetes, or complex anatomy that stents cannot address durably. The Clinical Criteria Used to Choose Between Bypass Surgery vs Angioplasty The bypass surgery vs angioplasty decision is not made on a single factor. It requires reviewing the angiogram against a structured set of criteria. At Yatharth Hospital, every complex case is reviewed by both Dr. Ved Prakash (cardiac surgeon) and an interventional cardiologist before a recommendation is made — this is called the Heart Team approach, and it is the international standard. 1. Number of Blocked Arteries Single-vessel disease: Angioplasty is usually appropriate if the lesion is technically suitable Two-vessel disease: May be treated with either — depends on location and patient factors Three-vessel disease (triple vessel disease): Bypass surgery vs angioplasty — bypass surgery is strongly preferred. Multiple stents in all three arteries have higher restenosis rates and do not match the durability of a triple bypass 2. Left Main Coronary Artery Disease The left main artery supplies 70% of the heart muscle. A significant blockage here is a surgical emergency — or at minimum, a case where bypass surgery vs angioplasty must be carefully weighed by a Heart Team. Current guidelines recommend bypass surgery for most left main disease, particularly when combined with other vessel disease. 3. Diabetes This is the single most important factor that tips the bypass surgery vs angioplasty decision toward bypass for multi-vessel disease. The landmark FREEDOM trial showed that diabetic patients with multi-vessel disease who received bypass surgery had significantly lower mortality and heart attack rates at 5 years compared to angioplasty. Diabetic vessels tend to re-block stents at higher rates — making the more durable bypass graft the better long-term choice. 4. The SYNTAX Score The SYNTAX score is an angiographic scoring system that quantifies the complexity of coronary artery blockages. A higher score means more complex disease. In general: Low SYNTAX score (0–22): Either bypass surgery or angioplasty — angioplasty outcomes are equivalent Intermediate SYNTAX score (23–32): Individualised decision — Heart Team required High SYNTAX score (33+): Bypass surgery is strongly preferred — angioplasty outcomes are significantly inferior 5. Heart Muscle Function (Ejection Fraction) When the heart’s pumping function is significantly reduced (ejection fraction below 35%), bypass surgery has been shown to improve survival more reliably than angioplasty — because restoring complete blood supply to the struggling heart muscle requires grafting all diseased vessels, which multiple stents rarely achieve as completely. 6. Age and Surgical Fitness For very elderly patients (over 80) or those with severe lung disease, kidney failure, or other conditions that make surgery high-risk — angioplasty may be preferred even when bypass surgery would normally be the better anatomical choice. The bypass surgery vs angioplasty decision always accounts for the patient’s overall health, not just the angiogram. Bypass Surgery vs Angioplasty — Side-by-Side Comparison Factor Bypass Surgery (CABG) Angioplasty (PCI) Recovery time 6–12 weeks 1–3 days Best for diabetes + multi-vessel Yes — strongly preferred Higher restenosis risk Left main disease Preferred in most cases Only in selected anatomy Graft / stent durability LIMA graft: 15–20+ years Drug-eluting stent: 10–15 years Three-vessel disease Strongly preferred High SYNTAX score → inferior outcomes Blood thinners needed Aspirin only (lifelong) Aspirin + Clopidogrel (12 months minimum) Can be repeated if it fails Yes, but higher risk redo Yes, repeat angioplasty or bypass When Bypass Surgery vs Angioplasty Is Not Clear-Cut — Get a Second Opinion If your cardiologist has recommended angioplasty for multi-vessel disease and you are diabetic — or if you have been offered bypass surgery and want to understand whether angioplasty is viable — a cardiac second opinion in Delhi NCR from a CTVS surgeon who reviews your angiogram independently is the most important step before making a decision. Share your angiogram CD and report via WhatsApp with Dr. Ved Prakash for a pre-assessment. Frequently Asked Questions — Bypass Surgery vs Angioplasty Is bypass surgery vs angioplasty always a surgeon’s decision? No — the decision should be made jointly by an interventional cardiologist and a cardiac surgeon reviewing the angiogram together. A Heart Team approach using the SYNTAX score is the international standard. Any patient offered one option without this joint review should ask why. Which is better — bypass surgery or angioplasty? For single, simple blockages in otherwise healthy patients — angioplasty is usually sufficient. For three-vessel disease, left main disease, or diabetic patients with multiple blockages — bypass surgery gives more durable long-term results. There is no universal winner; the anatomy of the blockages decides. Can bypass surgery be done after failed angioplasty? Yes — bypass surgery is commonly performed after a stent fails (restenosis) or when multiple stents have been placed and further angioplasty is no longer feasible. It

Life after bypass surgery is significantly better for most patients than life before it — less chest pain, better breathing, more energy, and a reduced risk of heart attack. But the weeks between leaving the operating theatre and reaching full recovery require patience, the right information, and realistic expectations. Dr. Ved Prakash, Director of CTVS at Yatharth Super Speciality Hospitals, Greater Noida, has guided hundreds of patients through bypass surgery recovery. This is what actually happens, week by week.   Before We Begin — What Most Patients Feel in the First Days Immediately after bypass surgery, most patients are surprised by three things. First, how alert they feel once the anaesthesia wears off. Second, that the breathing tube is usually removed within 6–8 hours — far sooner than they expected. Third, that they are asked to sit up and take a few steps as early as Day 2. Recovery from bypass surgery is faster than most patients imagine — because the goal throughout is to get the heart and body moving again as soon as safely possible. Week-by-Week Bypass Surgery Recovery Timeline Days 1–2: Cardiac ICU You wake up in the cardiac ICU with monitoring lines and a breathing tube — both are removed within hours once you are stable Pain is managed continuously with IV medications — the nurses ask about your pain level regularly A physiotherapist visits on Day 1 to guide you through breathing exercises — these are critical for preventing lung complications You will be sitting up in a chair by Day 2 in most cases Chest drain tubes are usually removed on Day 2 Days 3–7: Hospital Ward You are moved from ICU to the general cardiac ward once stable Short walks in the corridor begin — typically 50–100 metres initially, increasing each day Eating and drinking normally resumes The chest wound is checked and dressed daily Medications are reviewed and finalised before discharge — aspirin, statins, beta-blocker are standard Most patients are discharged on Day 7–10 Weeks 2–4: Home Recovery The sternum (breastbone) is healing — it takes 6–8 weeks to fully unite. During this time, do not push yourself up from chairs using your arms, do not lift anything heavier than a glass of water, and do not drive Walk daily — start with 5–10 minutes and increase by 2–3 minutes each day as tolerated Shower is permitted once wounds are dry and sealed — usually by Day 10–12 Sleep is often interrupted in the first 2–3 weeks — this is normal and temporary Mild depression or emotional low is common in the first 2–3 weeks — it resolves as energy and confidence return First outpatient follow-up is at 2 weeks for wound check and blood tests Weeks 5–6: Healing Milestone The sternum is now mostly healed — gentle arm use and light daily activities resume Walking 20–30 minutes daily is the goal by Week 6 Most patients notice a real improvement in how they feel — chest pain is gone, breathing is easier, energy is returning You may return to light desk work from home if energy allows Driving is permitted at 6 weeks if the sternum feels stable and you can perform an emergency stop without hesitation Weeks 7–12: Return to Normal Life Most patients return to their regular routine — including work — between 8 and 12 weeks Cardiac rehabilitation (supervised exercise program) typically begins at Week 6–8 — strongly recommended for all bypass surgery patients Sexual activity can usually resume at Week 6–8 when sternum is fully healed Air travel is generally safe at 6–8 weeks with medical clearance Lifting heavier objects — up to 5 kg — is usually permitted by Week 8–10 What You Should Not Do After Bypass Surgery Activity When It Is Safe Driving 6 weeks minimum Lifting over 5 kg 8–10 weeks Return to desk work 6–8 weeks Return to physical work 12 weeks minimum Swimming 12 weeks (chest wound must be fully healed) Air travel 6–8 weeks with medical clearance Medications After Bypass Surgery — What and Why Most bypass surgery patients are discharged on the following medications — do not stop any of them without consulting your doctor: Aspirin: Keeps the bypass grafts open by preventing clotting. Lifelong. Statin (e.g. Atorvastatin): Controls cholesterol and protects the arteries. Lifelong. Beta-blocker (e.g. Metoprolol): Controls heart rate and reduces cardiac workload. Usually for at least 12 months, often longer. ACE inhibitor (e.g. Ramipril): Protects heart muscle function. Often long-term especially if ejection fraction was low. Warning Signs After Bypass Surgery — When to Seek Help Immediately High fever (above 101°F / 38.5°C) — may indicate wound infection Redness, swelling, or discharge from the chest wound or leg wound Chest pain — new or different from before surgery Significant breathlessness at rest Leg swelling or calf pain — possible DVT Sudden weakness or slurred speech — seek emergency care immediately Frequently Asked Questions — Life After Bypass Surgery How long does it take to fully recover from bypass surgery? Most patients feel significantly better by 6 weeks and return to full normal life by 8–12 weeks. The sternum takes 6–8 weeks to fully heal — during this period physical restrictions apply. After 12 weeks, there are generally no long-term restrictions on activity. Will I feel better after bypass surgery than before? For the vast majority of patients — yes, dramatically. The relief of restored blood flow to the heart eliminates angina completely in most cases. Patients frequently report being able to walk, climb stairs, and exercise without chest pain or breathlessness for the first time in years. Is depression common after bypass surgery? Yes — a significant proportion of bypass surgery patients experience mild depression or emotional low in the first 2–4 weeks after surgery. This is partly hormonal (the body’s response to major surgery) and partly psychological. It almost always resolves as physical recovery progresses. Talk to your cardiac team if it persists beyond 4–6 weeks. How long do bypass grafts last? The LIMA
