Risk Factors

Know what puts you at risk

  • Hypertension (above 130/80 mmHg)
  • LDL cholesterol above 100 mg/dL
  • Type 2 diabetes or prediabetes
  • Smoking — even 1–5 cigarettes daily
  • Family history of MI before age 55
  • Sedentary lifestyle and central obesity
02

Warning Signs

Symptoms that demand immediate attention

  • Chest pressure, tightness or squeezing
  • Pain radiating to jaw, arm or back
  • Unexplained breathlessness at rest
  • Palpitations lasting more than 30 seconds
  • Sudden dizziness or near-syncope
  • Cold sweat with nausea

Longevity Protocols

Evidence-based heart health strategies

  • Zone 2 cardio 150 min/week minimum
  • Mediterranean-DASH dietary hybrid
  • Sleep 7–9 hours — cardiac repair window
  • Statin therapy if 10-year risk exceeds 7.5%
  • Annual cardiac screening after age 40
  • Stress reduction — cortisol damages endothelium

Common Questions

Answers from our cardiologists to the questions they hear most often.

You should seek immediate emergency care if you experience chest pain, pressure, or tightness lasting more than 5 minutes, especially if accompanied by breathlessness, sweating, or arm/jaw pain. For non-emergency symptoms — such as occasional palpitations, mild exertional chest discomfort, or unexplained fatigue — schedule a consultation within 48 hours. Do not wait for symptoms to resolve on their own. Early evaluation prevents the majority of adverse cardiac events.

An echocardiogram is a real-time ultrasound of your heart that evaluates its structure, pumping function, valve integrity, and wall motion. It is the single most informative non-invasive cardiac test available. You may benefit from one if you have a new murmur, unexplained breathlessness, prior heart attack, hypertension with end-organ involvement, or are being evaluated for surgery. Our 3D Echo suite provides sub-millimetre resolution that standard 2D studies cannot match.

For low-risk individuals with no symptoms or family history, we recommend a baseline cardiac evaluation at age 40, then every 2–3 years. If you have hypertension, diabetes, dyslipidaemia, or a first-degree relative with premature heart disease, annual screening is appropriate. High-risk individuals — smokers, those with established atherosclerosis, or prior cardiac events — require 6-monthly monitoring. Our preventive cardiology programme offers personalised screening schedules based on your genomic and metabolic risk profile.

A heart attack (myocardial infarction) occurs when a coronary artery is blocked, cutting off blood supply to heart muscle — the heart continues beating but is being damaged. The patient is conscious and in pain. Cardiac arrest is when the heart stops beating entirely due to a lethal arrhythmia, causing the patient to collapse and become unresponsive. A heart attack can trigger cardiac arrest, but they are distinct events requiring different responses. For cardiac arrest: call 112 and begin CPR immediately. For heart attack: call 112, give aspirin 300mg if available, and do not let the patient walk. Both are emergencies — every minute matters.
