What is ischemic heart disease?

Ischemic Heart Disease (IHD)—also known as coronary heart disease (CHD)—is a condition caused by reduced blood supply to the heart muscle due to narrowing or blockage of the coronary arteries. These arteries supply oxygen-rich blood to the heart, and when they are narrowed, the heart doesn’t get enough oxygen, a condition called ischemia. If severe or sudden, this can lead to a heart attack. Is there a difference between CAD and CHD? The terms coronary artery disease (CAD) and coronary heart disease (CHD) are often used interchangeably, and in everyday clinical practice, they usually mean the same thing. Technically speaking:
  • CAD refers to the process—plaque buildup inside the coronary arteries
  • CHD/IHD refers to the result of that process, where reduced blood flow causes symptoms or heart damage
Plaque buildup often begins early in life and progresses over time. Ischemia can be:
  • Chronic – gradual narrowing causing reduced blood flow (stable angina)
  • Acute – sudden plaque rupture with clot formation, leading to a heart attack
Common symptoms of ischemic heart disease
  • Chest pain or pressure (angina)
  • Pain in the upper body (arms, neck, jaw, back)
  • Shortness of breath
  • Excessive sweating
  • Indigestion or heartburn-like sensation
  • Nausea or vomiting
  • Dizziness or lightheadedness
  • Fast or irregular heartbeat
Symptoms often appear during physical activity, emotional stress, cold weather, or excitement, when the heart needs more oxygen than it’s receiving. Treatment options Treatment depends on the severity of artery blockage and overall heart health. Options may include:
  • Medications to improve blood flow and reduce risk factors
  • Key hole heart operations in Bangalore (minimally invasive procedures)
  • Robotic assisted heart operations in Bangalore for precision and faster recovery
  • Angioplasty, stenting, or open heart surgery, when needed
Choosing the best heart doctor, cardiologist, or cardiothoracic surgeon in Bangalore is crucial for accurate diagnosis and personalized treatment—especially for complex cases requiring advanced cardiac care. How to reduce your risk You can significantly lower your risk of ischemic heart disease by:
  • Staying physically active
  • Maintaining a healthy weight
  • Avoiding all tobacco products
  • Eating a heart-healthy diet rich in fruits, vegetables, and whole grains
  • Managing blood pressure, cholesterol, and diabetes with prescribed medications
Early diagnosis and expert care—whether from the best cardio-vascular surgeon in Bangalore or a multidisciplinary cardiac team—can prevent complications and greatly improve quality of life. If you’re experiencing symptoms or have risk factors, timely consultation can make all the difference.
