Best Cardiologists for Coronary Artery Disease in Chennai, India

Coronary artery disease is the narrowing or blockage of one or more of the coronary arteries — the vessels that deliver oxygen-rich blood to the heart — usually caused by the progressive accumulation of cholesterol-containing plaques within the artery walls. It is one of the leading causes of death and disability worldwide.

Common presentations include chest pain or pressure (angina) that may radiate to the arm, jaw, or back, shortness of breath on exertion, unusual fatigue, and palpitations; in some people, the condition is entirely silent until a cardiac event occurs. The severity of symptoms does not always reflect the degree of arterial narrowing, and some patterns — such as stable versus unstable angina — carry very different levels of urgency. Symptoms alone are not sufficient to confirm a diagnosis or determine treatment; formal clinical evaluation and investigation are always required.

Diagnosis typically begins with a detailed cardiovascular history, risk-factor assessment, and a resting electrocardiogram (ECG). Depending on findings, further investigations may include an exercise stress test, stress echocardiography, cardiac CT angiography, or nuclear perfusion imaging to detect and quantify areas of reduced blood flow. When significant disease is suspected, coronary angiography — an X-ray imaging procedure using contrast dye — provides a definitive anatomical picture of the coronary arteries and the location and severity of any blockages, helping to categorise disease as single-, double-, or triple-vessel and informing decisions about the most appropriate intervention.

Treatment is tailored to the individual based on symptom burden, the number and location of affected vessels, overall heart function (typically measured by left ventricular ejection fraction), and coexisting health conditions. For many people, particularly those with stable, less extensive disease, optimal medical therapy combined with supervised lifestyle changes is the first-line approach; procedural intervention is added when symptoms are inadequately controlled or when the anatomy or functional tests indicate a clear benefit. Procedural options available through our directory include coronary angioplasty and stent placement (PCI) for suitable lesions, and coronary artery bypass grafting (CABG) — including minimally invasive CABG — for more complex or multi-vessel disease; the most appropriate strategy depends entirely on an individual assessment by a qualified specialist team.

Non-procedural management plays a central role in CAD at every stage and includes evidence-based medications such as statins, antiplatelet agents, beta-blockers, and ACE inhibitors or ARBs, alongside structured lifestyle modification — cardiac-specific dietary changes, regular supervised exercise, smoking cessation, and blood pressure and blood glucose control. Cardiac rehabilitation programmes, where available, are strongly recommended following any acute event or procedure and have been shown to meaningfully reduce the risk of future events. For many patients with stable disease, this approach alone provides effective long-term control, though regular monitoring is essential to detect any progression.

Coronary Artery Bypass Grafting (CABG) may be considered when conservative or medical options have not achieved enough improvement, or when the severity of the condition warrants it. The decision depends on clinical assessment, expected benefits and individual risks.

CAD is typically evaluated and managed by a cardiologist, who coordinates medical therapy, imaging, and risk stratification; when bypass surgery is indicated or being considered, a cardiothoracic surgeon joins the care team. Complex or high-risk cases are ideally discussed by a multidisciplinary heart team — including interventional cardiologists, cardiothoracic surgeons, and cardiac anaesthetists — before a treatment decision is made.

When selecting a specialist or centre for CAD, it is worth looking into the team's experience with the specific procedure under consideration (such as PCI versus CABG or minimally invasive techniques), the centre's volume of coronary cases and published or audited outcomes, access to a full multidisciplinary heart team, and the availability of structured cardiac rehabilitation and long-term follow-up support.
