Coronary Artery Disease (CAD): Symptoms & Treatment

Have you ever felt a sudden tightness in your chest during a walk or while climbing stairs? It might seem like nothing, but it could be a sign of something serious, like coronary artery disease, or CAD. In India, where busy lifestyles and changing diets are common, heart problems like this are on the rise. CAD happens when the arteries that supply blood to your heart get narrow or blocked, often due to plaque buildup. This can lead to serious issues if not caught early. In this post, we'll break down what CAD is, its symptoms, causes, and how it's treated. Whether you're worried about your own health or a loved one's, understanding this can help you take the right steps.

What is Coronary Artery Disease?

Coronary artery disease, also known as coronary heart disease or ischemic heart disease, is a common type of heart disease. It affects the coronary arteries—the main blood vessels that carry oxygen-rich blood to your heart muscle. Over time, these arteries can develop plaque, which is made up of cholesterol, fat, and other substances. This buildup causes narrowing of the coronary arteries, reducing blood flow and making it hard for your heart to work properly.

In simple words, think of your arteries as pipes. If gunk builds up inside, less water (or blood) can flow through. This can lead to problems like chest pain or even a heart attack, which is a myocardial infarction in medical terms. CAD is part of a bigger group called cardiovascular diseases, and it's often linked to atherosclerosis, where arteries harden and narrow.

In India, factors like high stress, smoking, and diets rich in oily foods make CAD more common. It's not just an "old person's disease"—it can start in your 30s or 40s if risk factors pile up.

Causes and Risk Factors of CAD

CAD doesn't happen overnight. It builds up over the years due to a mix of lifestyle and health issues. Here's what often contributes:

High cholesterol levels: Too much "bad" cholesterol (LDL) can form plaque in your arteries.
High blood pressure: This damages artery walls, making it easier for plaque to stick.
Smoking: It harms blood vessels and speeds up plaque buildup.
Diabetes: High blood sugar can injure arteries over time.
Obesity and lack of exercise: Extra weight strains your heart, and sitting too much doesn't help blood flow.
Family history: If close relatives have had heart disease, your risk goes up due to the genetics of coronary artery disease.
Other factors: Age (over 45 for men, 55 for women), stress, and poor diet play roles, too.

Cluster risks like these can lead to related issues, such as peripheral artery disease or carotid artery disease, where similar narrowing happens in other body parts. In India, where diabetes rates are high, many people face a higher chance of CAD turning into acute coronary syndrome—a sudden blockage that needs quick care.

To keep it in check, knowing your risks is key. Regular check-ups can spot early signs, like high serum fibrinogen or cholesterol deposits.

Symptoms of Coronary Artery Disease

Symptoms of CAD can be sneaky. Some people have none until a big problem hits, like a heart attack. But watch for these common signs, especially if they happen during activity:

Chest pain or angina: This feels like pressure, tightness, or squeezing in your chest. It might spread to your arms, neck, jaw, or back.
Shortness of breath: You might feel out of breath even with light tasks.
Fatigue: Unusual tiredness that doesn't go away with rest.
Heart palpitations: A racing or irregular heartbeat.
Pain in other areas: Discomfort in the shoulders, arms, or stomach that feels like indigestion.
Sweating or nausea: Cold sweats or feeling sick, especially with chest pain.

Women might have different symptoms, like jaw pain or extreme fatigue, without strong chest pain. If CAD worsens, it can cause acute coronary syndromes, leading to unstable angina or myocardial infarction.

Important note: If you have sudden, severe chest pain, call for help right away—it could be a heart attack. In India, quick access to a multi-speciality hospital in Guwahati or similar cities can make a big difference.

Key Diagnostic Methods for CAD:

Electrocardiogram (ECG): Records the heart’s electrical signals using skin electrodes to identify irregular rhythms.
Stress Test: Monitors your heart while you exercise, helping detect reduced blood flow during physical activity.
Coronary Angiography: Uses dye and X-rays to map narrowed or blocked coronary arteries.
CT Angiography: A non-invasive scan that shows detailed images of the coronary arteries, calcium buildup, and possible blockages.
Echocardiogram: Uses sound waves to create moving images of the heart, showing blood flow and pumping function.
Blood Tests: Measure cholesterol, blood sugar, and heart damage markers, helping to assess risks like high cholesterol or heart attack.

If you live in a city like Guwahati, visiting a cardiology hospital in Guwahati makes accessing these tests simple. Early detection is very important, as it can help prevent serious complications such as heart failure.

Treatment Options for CAD

Treatment aims to ease symptoms, improve blood flow, and lower risks. It depends on how severe your CAD is—mild cases might need just changes in daily habits, while advanced ones require procedures.

Lifestyle Changes

These are the foundations for managing CAD:

Eat heart-healthy foods: Focus on fruits, veggies, whole grains, and lean proteins. Cut back on fatty foods and salt to fight plaque buildup.
Exercise regularly: Aim for 30 minutes a day, like walking or yoga, to strengthen your heart.
Quit smoking: It’s one of the best things you can do—your risk drops fast.
Manage weight and stress: Lose extra pounds and try relaxation techniques to keep blood pressure down.

Medications

Doctors often prescribe:

Statins: To lower cholesterol and slow plaque growth.
Antiplatelets like aspirin: Prevent blood clots in narrowed arteries.
Beta-blockers or ACE inhibitors: Control blood pressure and ease heart strain.
Nitrates: For quick relief from angina pain.

For those with diabetes, controlling blood sugar is crucial to avoid worsening vascular diseases.

Procedures and Surgery

If meds aren't enough:

Percutaneous coronary intervention (PCI): A balloon opens the artery, and a coronary stent keeps it wide.
Coronary artery bypass grafting (CABG): Surgeons use a healthy vessel to bypass the blocked one.
Other options: Like laser treatments or enhanced external counterpulsation for better blood flow.

In cases of obstructive coronary artery disease, these can save lives. Recovery involves cardiac rehab programs, which include exercise and education.

Treatment for acute events, like management of acute coronary syndromes, might include blood-thinning medicine like Plavix.

Preventing Coronary Artery Disease

Prevention is better than cure, especially for cardiovascular health. Start with:

Regular health checks to catch issues early.
A balanced diet low in cholesterol plaques.
Staying active to avoid sedentary risks.
Controlling conditions like high blood pressure or diabetes.

Studies show that lifestyle tweaks can cut CAD risk by up to 80%. In India, where heart disease is a top killer, simple steps like these matter a lot.

Frequently Asked Questions

1. What are the early signs of coronary artery disease?

The most common early sign is angina—a tight, squeezing chest discomfort that may also radiate to the jaw, arm, or back. Other early clues include shortness of breath during light activity, fatigue, palpitations, sweating, or nausea. Some individuals, especially women, may experience subtle symptoms like jaw or shoulder pain instead of classic chest pain.

2. How is coronary artery disease diagnosed?

CAD is diagnosed through a combination of medical history, physical exam, and diagnostic tests. Common tests include ECG (electrocardiogram), stress tests, echocardiograms, CT or coronary angiography, and blood tests for cholesterol and heart markers. Heart MRI or calcium scoring may also be used.

3. Can coronary artery disease be prevented?

While some risk factors aren’t controllable, CAD can be largely prevented by adopting heart-healthy habits: balanced diet, regular exercise, quitting smoking, managing blood pressure, cholesterol, and diabetes. These lifestyle changes significantly reduce risk and slow disease progression.

4. Is there a difference between aspirin and newer medications like clopidogrel for CAD prevention?

Yes—recent research shows that clopidogrel, a widely available blood-thinning medication, reduced serious cardiac events by about 14% more than aspirin in people with CAD, with similar safety. This finding, published in The Lancet, is prompting updates in treatment guidelines.
