Ischemic Heart Disease (IHD), often called Coronary Artery Disease, is the leading cause of death worldwide. It occurs when the arteries supplying blood to the heart muscle become narrowed or blocked, usually by a buildup of plaque.
The danger of IHD is that it can be a “silent killer.” To help you recognize the warning signs before they lead to a heart attack, we use the mnemonic: ISCHEMIA.
The ISCHEMIA Mnemonic Signs & Symptoms
Knowing these symptoms can save a life. If you or someone you know experiences these regularly—especially during physical exertion—it’s time to see a cardiologist.
| Letter | Symptom | Why it Happens |
| I | Indigestion & Nausea | The heart and stomach share nerve pathways. Heart pain is often mistaken for heartburn. |
| S | Sweating & Light-headedness | A struggling heart triggers the “fight or flight” system, causing cold sweats (diaphoresis). |
| C | Chest Pain / Congestion | That classic feeling of pressure, squeezing, or fullness in the center of the chest. |
| H | Heart Rate Faster | Tachycardia occurs as the heart tries to compensate for the lack of oxygenated blood. |
| E | Edema & Abdominal Swelling | When the heart pumps inefficiently, fluid backs up in the legs (edema) or abdomen. |
| M | Mild Dizziness | Reduced blood flow to the brain can cause a “faint” feeling or vertigo. |
| I | Ischemic Cardiac Arrest | The most severe stage: when the heart’s electrical system malfunctions due to lack of oxygen. |
| A | Angina | Recurrent chest pain that often happens during exercise and goes away with rest. |
Understanding the “Plumbing” Problem
Ischemia literally means “restricted blood supply.” Think of your coronary arteries as pipes. Over time, cholesterol and fats create a “sludge” (plaque) that narrows the pipe.
- Stable Ischemia: You feel symptoms only when you “push” the heart (like climbing stairs).
- Unstable Ischemia: The symptoms happen at rest. This is a medical emergency.
How to Reduce Your Risk
The good news? Ischemic Heart Disease is often preventable or manageable through lifestyle changes:
- Monitor Blood Pressure: High pressure damages artery walls, making it easier for plaque to stick.
- Manage Cholesterol: Lowering LDL (the “bad” cholesterol) prevents further blockage.
- Watch for “Atypical” Symptoms: Women, elderly patients, and diabetics often don’t get chest pain—they might only experience the I (Indigestion) or S (Sweating) from our mnemonic.
The ISCHEMIA mnemonic is a life-saving tool for your mental first-aid kit. If the “plumbing” of the heart is blocked, the body will send these signals. Listen to them!
