Causes of Heart Attack In Young Age: Tips To Avoid

Meeting a 38 year old with a heart attack is no longer unusual in a cardiac ward. Check their history and the same pattern keeps showing up: smoking or poor sleep, blood sugar or cholesterol never tested, and a parent with early heart disease. No single habit does it. The mix does. Most of those risks can be measured and changed, which is why finding them early counts for more than any treatment later.

According to Dr. Vishal Khullar, a leading Cardiac Surgeon in Mumbai, “Patients in their thirties often tell me they were too fit for this. Arteries don’t read birth certificates. Smoke and sleep five hours a night for ten years and plaque builds quietly. You feel fine right up until you don’t, and for plenty of my patients the attack was the first sign.”

In research, “young” usually means under 45, and sometimes up to 55. The trend is moving the wrong way. In one large registry, adults aged 40 or below accounted for a bigger share of heart attacks each year from 2007 to 2016, rising about 1.7 percent annually.

• Lifestyle: Tobacco does the most harm. It narrows the arteries and cuts the oxygen supply to your heart. Hours at a desk, fast food, regular heavy drinking and sleep under six hours compound it.
• Metabolic: Diabetes, hypertension, raised cholesterol and extra weight often creep in during your 20s with no symptoms. Autoimmune disorders add risk too. The fittest looking person in the office may simply never have had a blood test.
• Family history: If your father or brother had heart disease before 55, or your mother or sister before 65, your own risk goes up. Inherited high cholesterol is another route, and it can affect slim, active people too. Get tested.
• Rarer triggers: Cocaine and other stimulants, clotting disorders, coronary artery spasm, and arteries malformed from birth. In teenagers, that’s where doctors usually look first. Stress seldom causes an attack by itself, but it feeds smoking and bad sleep.

Where several arteries are narrowed, bypass surgery often gives blood flow a more lasting fix.

Heart attacks don’t all look alike.

• Warning signs: Look for chest pressure, breathlessness, cold sweat, nausea, or pain spreading to the arm, jaw or back. Young adults blame acidity. Some feel drained or short of breath for weeks beforehand. Many get no warning.
• Prevention at home: Start by quitting tobacco. Next, aim for 150 minutes of brisk walking a week, more vegetables, fruit and nuts, and seven to nine hours of sleep. Get blood pressure, cholesterol and sugar tested every year.
• Night time risk: Sleep apnoea and uncontrolled hypertension are the main causes, so have both checked. Take prescribed medicines on time. Even a sudden night time attack rarely comes out of the blue. Plaque builds for years first.
• If symptoms start: Call 112 or 108 right away, and don’t drive yourself to hospital. If you aren’t allergic, chew one 300 to 325 mg aspirin while help is on the way. Viral 7 second and 30 second tricks don’t work, and neither do home remedies. Every minute of delay costs heart muscle.

Most of these risks come from routine, and our guide on daily heart habits walks through the fixes.

Dr. Vishal Khullar holds an MBBS from B.J. Medical College, Pune, and trained in general surgery at KEM Hospital and in cardiovascular and thoracic surgery at Bombay Hospital. He later completed clinical fellowships at Mayo Clinic and Cleveland Clinic in the US. With over 30 years in practice and more than 7,000 heart surgeries, he serves as Director of cardiovascular and thoracic surgery at Fortis Hospital Mulund and Fortis S L Raheja Hospital, Mahim. After a heart attack, his role is surgical: bypass when several arteries are blocked, and repair of valve or heart muscle damage.
