Heart disease is a leading cause of death worldwide, affecting people from all walks of life. Despite its prevalence, heart disease is often preventable through lifestyle changes and awareness. This blog aims to provide you with comprehensive information on heart disease, from its types and symptoms to prevention tips, so you can take proactive steps towards a healthier heart.
What is Heart Disease?
Heart disease refers to various conditions that affect the heart’s function and structure. Here are some of the most common types:
- Arrhythmia: An abnormal heart rhythm.
- Atherosclerosis: Hardening of the arteries.
- Cardiomyopathy: Disease of the heart muscle.
- Congenital Heart Defects: Heart problems present at birth.
- Coronary Artery Disease (CAD): Plaque buildup in the arteries.
- Heart Infections: Conditions like endocarditis and myocarditis.
The term “cardiovascular disease” is often used interchangeably with heart disease, though it specifically refers to conditions affecting the blood vessels.
Who Gets Heart Disease?
Heart disease does not discriminate; it affects people of all ages, ethnicities, and backgrounds. Factors such as an unhealthy lifestyle, genetic predisposition, and pre-existing conditions can increase the risk. In India, almost half of the population is at risk due to various lifestyle factors, and these numbers are steadily rising.

Causes of Heart Disease
Heart disease is caused by a variety of factors, which differ depending on the type:
Arrhythmia Causes
- Diabetes
- Coronary Artery Disease (CAD)
- Heart defects
- High blood pressure
- Certain medications
Congenital Heart Defect Causes
These occur while a baby is developing in the womb. Some defects are serious and diagnosed early, while others may go undiagnosed for years.
Cardiomyopathy Causes
- Dilated Cardiomyopathy: Often caused by coronary artery disease or toxic substances.
- Hypertrophic Cardiomyopathy: Usually inherited, causing the heart muscle to thicken.
- Restrictive Cardiomyopathy: The heart muscle becomes rigid, often due to scar tissue.
Heart Infection Causes
- Bacteria
- Parasites
- Viruses
- Uncontrolled infections in the body
Risk Factors for Heart Disease
According to the CDC, around 47% of people in the United States have at least one risk factor for heart disease. These include:
- High blood pressure
- High cholesterol and low levels of high-density lipoprotein (HDL)
- Smoking
- Obesity
- Low physical activity
Preventing Heart Disease
Preventing heart disease involves taking proactive steps to manage risk factors and improve cardiovascular health. Dr. Vinayak Agarwal, Senior Director & Head Clinical Cardiology & Advanced Cardiac Imaging at Fortis Memorial Research Institute (FMRI), Gurugram advises, “Prevention is the key to combating heart disease. Adopting a heart-healthy lifestyle early significantly reduces the risk.”
Tips for Prevention
