Ischemic Heart Disease (IHD) Explained: What You Need to Know

Imagine your heart as a vibrant city with coronary arteries as the main highways delivering oxygen-rich blood to fuel its every beat. What will happen when these roads get narrowed with the plaque buildup (atherosclerosis)? Chances are, the blood will not be able to flow properly, starving your heart muscles. This restricted flow is known as ischemic heart disease (IHD), which can increase the risk of irregular heartbeats, myocardial infarction (heart attack), angina, and heart failure.

Hence, consult a heart specialist at the best cardiology hospital in Kolkata if you experience chest pain or discomfort known as angina pectoris, pain in the upper body, shortness of breath, indigestion that may feel like heartburn, nausea or vomiting, dizziness or lightheadedness, or a fast or irregular heartbeat. Only a medical expert can provide an accurate diagnosis and recommend the appropriate treatment.

What Happens in Ischemic Heart Disease?

Here are the key events that can happen in ischemic heart disease:

1. Plaque buildup (also known as atherosclerosis) is made up of cholesterol, fats, calcium, and inflammatory cells in the arteries. This can lead to narrowing of the arteries, which restricts blood flow.
2. The heart muscle (myocardium) does not receive sufficient blood, leading to myocardial ischemia. The heart struggles to function properly.
3. People may experience chest pain, pressure, or discomfort, typically during physical exertion or stress, known as angina pectoris.
4. If untreated, the arteries can get blocked completely, increasing the risk of heart muscle cells dying, irregular heart rhythms, and even a heart attack. 

Timely consultation from the best cardiologist in Kolkata can address the underlying cause and prevent further complications.

Can You Live With Ischemic Heart Disease?

Yes, through careful management, you can live a fulfilling, healthy life.

Can Ischemia Be Cured?

No, ischemia in advanced cases of IHD cannot be fully cured, as it stems from irreversible atherosclerosis damage. Thankfully, through proper lifestyle changes and management approaches, the blood flow can be restored and alleviate symptoms.

Causes of IHD (Ischemic Heart Disease)

The main cause is atherosclerosis, the buildup of plaque (cholesterol, fat, calcium) that narrows coronary arteries and blocks oxygen-rich blood flow to the heart.

Here are some of the risk factors:

• Hypertension (high blood pressure)
• Hyperlipidemia (high LDL cholesterol)
• Smoking
• Diabetes
• Lifestyle factors such as obesity, poor diet (high in fat/sodium), and low levels of physical exercise
• Family history/genetics
• Advanced age,
• Pre-existing inflammatory conditions

How Do Doctors Diagnose Ischemic Heart Disease?

The best cardiologist in Kolkata does the diagnosis through a combination of methods and tests, such as:

• Patient history
• Physical exams
• Electrocardiogram (ECG/EKG) spots irregularities
• Stress tests mimic physical exertion
• An echocardiogram assesses heart function
• Coronary angiography reveals blockages
• A blood test measures biomarkers such as troponin to confirm heart injury

Coronary Heart Disease vs Ischemic Heart Disease

Both are closely related terms and often used interchangeably

Term	The Subtle Difference	Description
CAD (Coronary Artery Disease)	Structural problem	Refers specifically to plaque buildup (atherosclerosis) in the coronary arteries, which narrows or blocks them.
IHD (Ischemic Heart Disease)	Functional consequence	Refers to the heart muscle not receiving sufficient blood because of narrowed arteries, causing symptoms like angina or ischemia.

FAQ's

Q1: What is the difference between Ischemic Heart Disease and a heart attack?
 A: Ischemic Heart Disease (IHD) is the underlying condition where narrowed arteries reduce blood flow to the heart. A heart attack (myocardial infarction) is the acute result of IHD, occurring when an artery becomes completely blocked, causing heart muscle tissue to die due to a total lack of oxygen.

Q2: Can Ischemic Heart Disease be reversed naturally? 
A: While the structural damage of atherosclerosis (hardened plaque) is generally not reversible, the progression of IHD can be halted. Through a heart-healthy diet, regular exercise, and smoking cessation, you can stabilize plaque, prevent further blockages, and significantly improve your heart's pumping efficiency.

Q3: Is walking good for Ischemic Heart Disease? 
A: Yes, walking is one of the best exercises for IHD patients as it improves cardiovascular circulation without putting excessive strain on the heart. The best cardiologists in Kolkata recommend at least 30 minutes of brisk walking daily, provided you do not experience chest pain or severe shortness of breath.

Q4: How do I know if my chest pain is Angina or just heartburn? 
A: Angina (related to IHD) typically feels like pressure, squeezing, or heaviness that may radiate to the jaw, neck, or left arm, often triggered by physical activity. Heartburn is usually a burning sensation in the upper chest or throat, often occurring after meals. Because the symptoms overlap, any new chest pain should be evaluated by a cardiologist at IRIS Hospital.

Q5: What are the primary risk factors for IHD in Indian adults? 
A: In India, high rates of diabetes, hypertension (high blood pressure), and a diet high in trans fats and sodium are the leading risk factors. Genetics also play a role, making early screening essential for individuals over the age of 40 or those with a family history of heart disease.
