Do you feel breathless climbing a few stairs? Or notice a strange tightness in your chest after a stressful moment?
Most people blame these signs on acidity, poor sleep, stress or aging. But sometimes, these are actually early signs of a blockage in the arteries that supply blood to your heart. Catching them early can help you get checked before it becomes serious. Keep reading to know the early signs you should not miss and when it is time to see a cardiologist.
Heart blockage is not a formal medical diagnosis. In everyday language, it usually refers to narrowing of the coronary arteries, the blood vessels that supply oxygen-rich blood to the heart muscle. Medically, this condition is called coronary artery disease (CAD).
This narrowing of arteries is usually caused due to atherosclerosis, where fatty deposits called plaque build up inside artery walls. As plaque increases, the artery may become narrower and reduce blood flow, particularly when the heart needs more oxygen during exercise or stress. In some cases, it can also lead to a blood clot, which may block the artery completely and cause a heart attack.
This plaque buildup happens slowly, over several years, and may not cause any noticeable symptoms in the early stages. That is why understanding the early warning signs is very important.
The early signs of heart-related problems may not feel urgent. They may even feel normal. But over time, they can slowly make you feel less fit and start affecting your health. Here are the common early signs of heart blockage you should not miss and if something feels off, seek medical evaluation.
Chest discomfort is one of the commonly known heart blockage symptoms. It may feel like:
The pain is commonly felt in the centre or left side of the chest, but heart blockage chest pain location can vary. The sensation may also spread to the arm, shoulder, jaw, neck or back.
Getting unusually breathless while walking, climbing stairs or performing activities you previously managed comfortably may be a warning sign. You can feel breathless with or without chest discomfort. It should be assessed when the discomfort is new, persistent or worsening.
Fatigue is easy to overlook because it has many possible causes. But if you are suddenly more tired than usual during routine tasks, that is worth paying attention to.
For example, if your usual 20 minute walk suddenly leaves you exhausted or you need to stop more frequently, tell your doctor about such signs.
Heart-related discomfort can travel beyond the chest. It may affect one or both arms, the shoulders, jaw, neck or upper back. This is particularly concerning when the discomfort comes with breathlessness, sweating, nausea or chest pressure.
Feeling dizzy once in a while does not necessarily mean your arteries are blocked. But if you suddenly feel lightheaded, weak or like you might faint, especially along with chest discomfort or breathlessness, it is worth getting checked.
Palpitations feel like racing, pounding, fluttering or skipped heartbeats. They are more commonly linked with heart rhythm problems than coronary artery blockage. Still, new palpitations that come along with chest pain, breathlessness or fainting should be evaluated timely.
Some people with coronary artery disease have few or no obvious symptoms, such as:
This creates an important misconception: absence of crushing chest pain does not necessarily mean the heart is healthy.
For people with diabetes, nerve damage can also reduce the ability to perceive pain normally.
The risk of coronary artery disease increases with:
Just having risk factors does not mean you have blocked arteries. But the more risk factors you have, the more it makes sense to get a preventive check-up.
There is not one standard test everyone goes through for a heart blockage diagnosis. Instead, your doctor tailors the investigation, factoring in your symptoms, risk factors and examination findings.
Treatment depends on the severity and location of disease, symptoms and overall cardiovascular risk.
Lifestyle Changes
This is usually the first line of defence. Eating healthy foods that are good for your heart, staying physically active in ways that suit your condition, keeping your weight in check and quitting tobacco can go a long way in slowing things down and lowering your risk.
Medicines
Depending on your condition, your cardiologist may prescribe medicines. Whatever is prescribed, stick to it exactly as advised, skipping doses or stopping on your own can undo the benefit.
Angioplasty and Stent
If an artery is significantly narrowed, doctors may perform an angioplasty. A balloon-tipped catheter is guided to the narrowed section and inflated to push the blockage aside and restore blood flow. In most cases, a stent, a small mesh tube, is then placed to hold the artery open and prevent it from narrowing again.
Coronary Artery Bypass Graft Surgery (CABG)
For more severe or widespread blockages, cardiothoracic surgeons may recommend CABG. It is a surgery that creates a new path for blood flow by using a healthy vessel from elsewhere in your body to bypass the blocked artery.
Depending on the stage of heart blockage, most cases need immediate surgical intervention, while some need a longer planned approach. In fact, many people manage the condition through lifestyle changes and medication alone, especially when the blockage is mild to moderate and caught early.
Heart-healthy eating, regular exercise, weight management and quitting tobacco and smoking can help in slowing down or even stabilising the disease. Certain medicines can also help control the underlying risk factors and reduce strain on the heart.
However, non-surgical management is applicable only in very early stages where a build-up is starting. This is especially true for those with a family history of heat blockage. If the blockage is severe, affects a critical part of the artery, or is causing significant symptoms, your cardiologist may recommend a procedure like angioplasty or, in more advanced cases, bypass surgery.
The right approach depends entirely on your individual diagnosis, so this is a conversation to have with your cardiologist rather than a decision to make on your own.
Seek emergency medical care if you develop new or severe chest pressure, squeezing or discomfort, particularly if it lasts several minutes, keeps returning or occurs with:
Do not try to determine at home whether the symptoms are acidity, anxiety or a heart attack take first aid for a heart attack
Heart disease can develop without causing obvious or severe symptoms. You may first notice that walking the same distance leaves you unusually breathless, everyday activities feel more tiring, or fatigue keeps returning without a clear reason.
If these changes are becoming chronic or you have multiple cardiovascular risk factors, a cardiology evaluation can help determine whether further testing is needed. At the CK Birla Hospital, Gurgaon, our Cardiology Department evaluates and manages coronary artery disease using a personalised approach based on symptoms, risk factors and diagnostic findings.
