Heart disease remains the top cause of death worldwide, yet many heart attacks result from long-term damage caused by everyday habits, health conditions, and genetics. Cardiologists emphasize that while we cannot control factors like age or family history, numerous lifestyle choices are within our control. By recognizing and addressing these risks early, individuals can significantly reduce the likelihood of heart attacks and other cardiovascular issues.
Dr Amit Bhushan Sharma, Director and Unit Head at Paras Health, highlights 15 habits and conditions that can quietly damage the heart:
- Smoking and secondhand smoke – Tobacco harms arteries, increases plaque buildup, and lowers oxygen in blood, while exposure to secondhand smoke also raises cardiovascular risks.
- Unhealthy diet and high salt intake – Diets rich in saturated and trans fats, cholesterol, and sodium contribute to high blood pressure, clogged arteries, and heart disease. Prioritize fruits, vegetables, and whole grains.
- Chronic stress – Long-term stress raises cortisol levels, promotes inflammation, and can trigger unhealthy coping mechanisms like overeating or smoking. Stress management through mindfulness, yoga, and regular walks can protect heart health.
- Uncontrolled diabetes – Elevated blood sugar damages blood vessels and encourages plaque buildup, increasing the risk of heart disease. Managing blood sugar through diet, exercise, and medication is crucial.
- Excess weight or obesity – Abdominal fat worsens cholesterol and triglyceride levels, contributing to hypertension and type 2 diabetes, all of which increase heart disease risk. Even modest weight loss benefits the heart.
- Sedentary lifestyle – Lack of exercise weakens the heart and worsens cholesterol, blood pressure, and blood sugar levels. Aim for at least 150 minutes of moderate activity weekly.
- Excessive alcohol – Heavy drinking raises blood pressure, weakens the heart muscle, and increases stroke risk. Moderation is advised: one drink daily for women and two for men.
- Neglecting oral health – Gum disease and poor dental hygiene allow bacteria into the bloodstream, promoting inflammation and increasing cardiovascular risk. Regular brushing, flossing, and dental visits help protect the heart.
- Persistent high blood pressure – Hypertension forces the heart to work harder, thickening the muscle and narrowing arteries. Regular monitoring and treatment reduce stroke and heart attack risk.
- Sleep apnea – Pauses in breathing during sleep reduce oxygen and strain the heart. Proper diagnosis and treatment, such as CPAP therapy, improve heart health.
- Overusing painkillers – Long-term NSAID use can raise blood pressure and heart attack risk. Medications should be taken only under medical guidance.
- Family history of heart disease – Genetics play a role, so people with a history of early heart disease in close relatives should be extra vigilant.
- Age and sex – Men face higher risk earlier, while women’s risk increases after menopause. Aging naturally stiffens arteries and weakens heart muscle.
- Skipping regular checkups – Routine medical visits detect silent issues like hypertension or high cholesterol, allowing timely interventions to prevent heart damage.
- Not taking prescribed medications – Failing to take drugs for blood pressure, cholesterol, or diabetes can increase the risk of severe heart events. Adherence is critical.
By addressing these 15 factors through lifestyle adjustments, medical management, and preventive care, individuals can safeguard their heart and reduce the risk of serious cardiovascular events.
