Coronary Heart Disease: A Silent Killer in India and the U.S.; Know These 6 Heart Attack Warning Signs

Coronary heart disease (CHD) remains the leading cause of death from heart-related conditions, claiming approximately 3,75,476 lives annually in the U.S., according to the New York State Department of Health.

In India, the situation is equally, if not more, alarming. The National Institutes of Health (NIH) reports that India bears one of the world’s highest burdens of cardiovascular disease (CVD).

Estimates over the decades show that CHD prevalence in India ranges between 1.6% to 7.4% in rural populations and 1% to 13.2% in urban populations—highlighting a concerning upward trend that demands awareness and early detection.

6 Warning Signs of a Heart Attack You Should Never Ignore

Given the high prevalence of cardiovascular conditions, recognizing the early warning signs of a heart attack can be life-saving. In a social media post dated March 6, Dr. Akshay Mahajan (MDDM, Cardiology) outlined six key symptoms that everyone should be aware of:

1. Chest pain or discomfort

2. Dizziness, fainting, or light-headedness

3. Rapid or irregular heartbeat

4. Shortness of breath

5. Cold sweat

6. Stomach discomfort or indigestion

These symptoms can strike suddenly and should not be ignored, especially in individuals with existing risk factors.

CRP Blood Test: A Vital Tool to Predict Heart Attack Risk

Beyond symptom awareness, preventive testing can make a critical difference. On June 16, cardiologist Dr. Yaranov shared an Instagram post emphasizing the significance of a lesser-known but powerful diagnostic tool: the CRP blood test.

“The blood test that could save your life — and it’s not cholesterol,” wrote Dr. Yaranov.
“CRP exposes silent inflammation that damages your arteries before you feel a single symptom. Even with ‘normal’ cholesterol, a high CRP means you’re still at risk.”

C-reactive protein (CRP) is a marker of inflammation in the body. Elevated levels can indicate arterial inflammation that may lead to heart attacks. Since many individuals are unaware of elevated CRP until it’s too late, regular screening—especially for those at risk—can be a crucial step in heart disease prevention.
