Doctors Warn of 5 Subtle Early Signs of Heart Blockage You Shouldn't Ignore

New Delhi: Doctors say heart disease often starts with mild symptoms. These early signs can be easy to brush off as fatigue or stress. But experts warn that some of them may signal a narrowing of the arteries that feed the heart. If ignored, this could lead to a serious heart attack or other cardiac emergencies.

What should you watch for?

Cardiologists point to a handful of warning signs that people should take seriously:

• Shortness of breath with little effort: Feeling unusually breathless after walking a few steps or climbing stairs can mean the heart isn’t getting enough blood. 
• Chest discomfort: A sense of pressure, heaviness, or tightness in the chest, especially during activity, may be more than indigestion.
• Unexplained tiredness: Persistent fatigue that doesn't match your usual activity level can be an early clue that the heart is struggling. 
• Dizziness or lightheadedness: Less blood reaching the brain can make you feel off balance or woozy. 
• Burning in the chest: Some patients report a burning sensation they mistake for acidity or gastric issues. 

Doctors stress that these symptoms often get worse with physical effort. They come on because plaque builds up in the coronary arteries, narrowing the paths that bring oxygen-rich blood to the heart.

When does mild become serious?

These early signs can start quietly and may be mistaken for common issues like tiredness or stress. But when they happen regularly, or in combination, it’s a signal to seek medical advice. Untreated blockage can escalate to chest pain, angina, heart attacks, and even sudden cardiac events. 

What can you do now?

Heart specialists say lifestyle changes can make a big difference. They recommend:

• Eating a diet rich in fruits, vegetables and whole grains.
• Staying active with regular walking or light exercise.
• Avoiding smoking and managing stress. 
• Regular checks for cholesterol, blood pressure and blood sugar.

Why early action matters?

Heart disease doesn't always announce itself with dramatic symptoms. Many people don't realise something is wrong until it's too late. Recognising and acting on early warning signs can help prevent serious outcomes and protect long-term heart health.
