A condition where narrowed heart arteries reduce blood flow to the heart muscle, causing chest pain and increasing heart attack risk.
Call emergency services immediately if you experience chest pain lasting more than a few minutes, pain spreading to your arm or jaw, shortness of breath, cold sweats, nausea, or lightheadedness. These may be signs of a heart attack requiring immediate treatment.
Find a Specialist NowIschemic heart disease, also known as coronary artery disease or coronary heart disease, stands as the number one cause of death in the Philippines, accounting for nearly 20% of all deaths in the country. Understanding this condition, its warning signs, and how to protect yourself is literally a matter of life and death.
Ischemic heart disease occurs when the coronary arteries—the blood vessels that supply oxygen-rich blood to your heart muscle—become narrowed or blocked. This narrowing is usually caused by atherosclerosis, a gradual process where fatty deposits called plaques build up inside the artery walls.
Think of your coronary arteries like pipes delivering water to your home. When these pipes become clogged with debris, water flow decreases. Similarly, when your coronary arteries become clogged with plaque, blood flow to your heart muscle decreases—a condition called ischemia. When the heart doesn't receive enough oxygen-rich blood, it can cause chest pain (angina) or, if severely blocked, a heart attack.
Ischemic heart disease typically develops over decades, often beginning in young adulthood:
Stage 1 - Early Plaque Formation: Damage to the inner lining of arteries (from high blood pressure, smoking, or high cholesterol) allows fatty deposits to begin accumulating. At this stage, there are usually no symptoms.
Stage 2 - Plaque Growth: Over years, these deposits grow larger and begin to narrow the arterial opening. The artery may still be able to supply enough blood at rest, but symptoms may appear during physical exertion.
Stage 3 - Significant Blockage: When an artery becomes 70% or more blocked, symptoms like angina become more frequent and may occur even at rest. The risk of heart attack increases substantially.
Stage 4 - Acute Event: A heart attack occurs when a plaque ruptures and a blood clot forms, completely blocking blood flow. Without immediate treatment, heart muscle begins to die within minutes.
One of the most important aspects of managing ischemic heart disease is recognizing symptoms early. The classic symptoms include:
Angina (Chest Pain): Often described as pressure, squeezing, tightness, or heaviness in the chest. This discomfort may spread to the shoulders, arms, neck, jaw, or back. Angina typically occurs during physical activity or emotional stress and improves with rest.
Atypical Symptoms: Women, diabetics, and elderly patients may experience less typical symptoms, including:
Understanding that heart disease doesn't always present with dramatic chest pain is crucial. Many Filipinos dismiss early warning signs as mere fatigue or indigestion, delaying potentially life-saving treatment.
While some risk factors for ischemic heart disease are beyond our control (such as age, gender, and family history), many are modifiable:
Diet: The traditional Filipino diet, while delicious, often contains high levels of sodium, saturated fats, and cholesterol. Lechon, crispy pata, and other beloved dishes, when consumed frequently, contribute to plaque buildup.
Rice Consumption: The high glycemic index of white rice, consumed in large quantities at most meals, can contribute to metabolic syndrome and increase heart disease risk.
Smoking: The Philippines has one of the highest smoking rates in Asia, with approximately 23% of adults smoking. Tobacco use dramatically increases cardiovascular risk.
Hypertension: Many Filipinos have uncontrolled high blood pressure, a major contributor to heart disease.
Diabetes: The high prevalence of diabetes in the Philippines compounds cardiovascular risk significantly.
The good news is that ischemic heart disease is largely preventable and, when present, manageable:
Heart-Healthy Eating: Adopt a diet rich in:
Regular Physical Activity: Aim for at least 150 minutes of moderate aerobic exercise weekly. Even walking for 30 minutes a day can significantly reduce heart disease risk.
Smoking Cessation: Quitting smoking is one of the most impactful changes you can make. Within one year of quitting, your heart disease risk drops by 50%.
Managing Related Conditions: Control blood pressure, cholesterol, and diabetes through lifestyle changes and medications as prescribed.
Stress Management: Chronic stress contributes to heart disease. Find healthy ways to manage stress through exercise, meditation, prayer, or time with loved ones.
Medication Adherence: If you've been diagnosed with heart disease or prescribed preventive medications, take them consistently as directed.
If you or someone nearby experiences symptoms of a heart attack, every minute matters. Remember:
In the Philippines, many barangays now have emergency response capabilities. Know your local emergency numbers and nearest hospitals with cardiac care facilities.
A diagnosis of ischemic heart disease doesn't mean life is over—it means life must change. With proper treatment and lifestyle modifications, many people with heart disease live long, active lives. Regular follow-ups with your cardiologist, adherence to medications, participation in cardiac rehabilitation, and commitment to heart-healthy living can make all the difference.
Your heart has been working for you every second of your life. Now is the time to start working for it.
