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

  • 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

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.
