Coronary Artery Disease (CAD)

Symptoms, Advanced Treatment and Bypass Surgery 

Ahmedabad

Coronary Artery Disease (CAD), also known as coronary heart disease (CHD) or ischemic heart disease, is the most common form of heart disease. It occurs when the major blood vessels that supply your heart muscle with oxygen-rich blood become narrow, stiff, or blocked.

This reduction in blood flow is caused by a process called atherosclerosis—the slow, progressive buildup of fatty deposits, cholesterol, and calcium (known as plaque) inside your arteries.

Think of your coronary arteries as multi-lane highways delivering fuel to your heart. Plaque buildup is like a long-term lane closure: traffic slows down, but cars can still pass. However, if that plaque suddenly ruptures, a blood clot forms rapidly. This acts like a concrete barrier blocking the entire road—stopping blood flow entirely and causing a heart attack (myocardial infarction).

As a highly accomplished cardiovascular and thoracic surgeon in Ahmedabad, Dr. Ishan Gohil specializes in advanced surgical revascularization, including minimally invasive techniques and Coronary Artery Bypass Grafting (CABG), to restore healthy blood flow and prevent life-threatening cardiac events.

Types of Coronary Artery Disease

CAD typically presents in one of two ways:

• Stable Ischemic Heart Disease: This is the chronic, slow-developing form. Your arteries narrow gradually over several decades. You might experience predictable chest discomfort during physical exertion, but the condition can often be managed day-to-day with lifestyle changes and medication.

• Acute Coronary Syndrome (ACS): This is a sudden, life-threatening medical emergency. It occurs when a plaque deposit suddenly ruptures, triggering a rapid blood clot that completely blocks the artery. This abrupt loss of oxygen to the heart muscle causes a heart attack.

Symptoms of CAD: The "Silent Killer"

Because plaque builds up over many years, you may have CAD for decades without realizing it. Often, the very first symptom of coronary artery disease is a sudden heart attack. When symptoms do appear, they typically include:

• Stable Angina: Temporary chest pain, tightness, pressure, or a squeezing sensation that typically triggers during physical exercise or emotional stress and goes away with rest or medication (like nitroglycerin).

• Shortness of Breath (Dyspnea): Feeling unusually winded or fatigued during basic, daily activities.

• Heart Palpitations: A sensation of a racing, fluttering, or skipping heartbeat.

Warning Signs of a Heart Attack: If you experience crushing chest pain radiating to your jaw, neck, back, or left arm, accompanied by cold sweats, dizziness, or severe nausea, call for emergency medical assistance immediately.

What Causes CAD and Who is at Risk?

The underlying driver of coronary artery disease is atherosclerosis. Plaque—composed of cholesterol, cellular waste, calcium, and fibrin—clogs the inner arterial walls, depriving the heart muscle of necessary oxygen and nutrients (myocardial ischemia).

While genetics play a role, many prominent risk factors can be actively managed and controlled:

Age: Men over 45; Women over 55

Tobacco Use: Smoking, vaping, or chewing tobacco

Family History: Early heart disease in close biological relatives

High Blood Pressure (Hypertension): Strains artery walls

Biological Sex: Men generally face higher early risks

High Cholesterol: High LDL ("bad") and low HDL ("good") levels

Chronic Conditions: Kidney disease or autoimmune disorders

Sedentary Lifestyle: Lack of regular physical exercise

Metabolic Factors: Type 2 Diabetes or Obesity (BMI greater than 25)

Poor Diet: High intake of saturated fats and refined sugars

Comprehensive Diagnostic Protocols

To determine the severity of arterial blockages and map out an effective treatment plan, Dr. Ishan Gohil utilizes advanced cardiac diagnostics:

• Electrocardiogram (ECG/EKG): Evaluates your heart's electrical rhythm to check for signs of past or active heart strain.

• Echocardiogram (Echo): Uses ultrasound waves to assess how well your heart muscle is pumping and check for valve abnormalities.

• CT Coronary Angiogram / Coronary Calcium Scan: Advanced imaging that non-invasively measures plaque and calcium deposits in your coronary arteries.

• Cardiac Catheterization (Angiography): A minimally invasive procedure where a catheter is threaded to your heart to inject a contrast dye, allowing surgeons to see the exact location and severity of blockages.

Treatment Options and Surgical Expertise

The goal of treating CAD is to manage symptoms, improve blood flow to the heart, and lower the risk of a heart attack. Depending on the progression of your disease, Dr. Ishan Gohil will recommend a tailored treatment pathway:

1. Lifestyle Optimization & Medications

For early-stage or stable CAD, conservative medical management is highly effective:

• Lifestyle Changes: Adapting a heart-healthy Mediterranean diet, starting structured exercise programs, and committing to complete tobacco cessation.

• Medications: Beta-blockers, ACE inhibitors, statins (to lower cholesterol), and antiplatelet drugs (like low-dose aspirin) to prevent clots.

2. Percutaneous Coronary Intervention (PCI / Angioplasty)

For localized blockages, a cardiologist may perform an angioplasty. A tiny balloon is inflated inside the blocked artery to push the plaque back, and a mesh tube called a stent is left behind to keep the artery open.

3. Coronary Artery Bypass Grafting (CABG)

When patients have multiple, complex blockages across several main arteries, bypass surgery (CABG) is the gold standard, most durable solution.

During this open-heart surgery, Dr. Ishan Gohil takes a healthy blood vessel from your leg (saphenous vein), arm (radial artery), or chest (mammary artery) and uses it to create a detour around the blocked portion of your coronary artery. This immediately restores rich blood flow directly to the oxygen-starved heart muscle.

Recovery and Long-Term Outlook

Your recovery timeline depends heavily on the type of procedure you receive:

• Following PCI (Angioplasty): Most patients can return to normal daily activities within a week.

• Following CABG (Bypass Surgery): Patients typically spend 5 to 7 days in the hospital, with a full recovery taking between 6 to 12 weeks. Participating in a structured cardiac rehabilitation program is highly recommended to safely rebuild heart strength, implement dietary changes, and manage stress.

While CAD cannot be entirely reversed, it can be successfully managed. By combining state-of-the-art surgical interventions with healthy lifestyle choices, you can protect your heart and live a long, active life.

Consult a Heart Specialist in Ahmedabad

Protecting your heart starts with early detection and specialized care. If you have been diagnosed with coronary artery blockages, or are experiencing symptoms like chest pain and unexplained shortness of breath, consult with Dr. Ishan Gohil in Ahmedabad for a comprehensive cardiac evaluation and personalized surgical care plan.
