A 100% blockage of the right coronary artery (RCA) is a critical heart condition that can lead to severe complications, including heart attacks and heart failure. This condition occurs when plaque build-up completely obstructs blood flow to a section of the heart, causing oxygen deprivation and potential tissue damage.
In Singapore, cardiovascular diseases remain a leading cause of death, making it crucial to seek prompt medical attention if you experience any heart-related symptoms. If you or a loved one have been diagnosed with RCA blockage, consulting a qualified cardiologist in Singapore can be lifesaving.

What Is A 100% Blockage Of The Right Coronary Artery?
The right coronary artery (RCA) is responsible for supplying blood to the right side of the heart, including the right atrium, right ventricle, and portions of the left ventricle. A complete blockage occurs when atherosclerosis (the build-up of cholesterol, fats, and other substances in the artery) completely cuts off blood supply.
This condition is also known as a chronic total occlusion (CTO). If untreated, it can result in myocardial infarction (heart attack), arrhythmias, or even heart failure.

Common Symptoms Of RCA Blockage
The symptoms of a 100% RCA blockage may vary depending on the severity of the condition. Some individuals experience mild symptoms, while others suffer from sudden, life-threatening events. Common signs include:
- Chest Pain (Angina): A tight, squeezing sensation in the chest, often triggered by physical activity or stress.
- Shortness Of Breath: Difficulty breathing, especially during exertion or while lying flat.
- Fatigue: Persistent tiredness even with minimal activity.
- Dizziness Or Fainting: Reduced blood flow to the brain may cause dizziness or loss of consciousness.
- Heart Palpitations: Irregular or rapid heartbeats.
- Cold Sweats & Nausea: These symptoms often accompany heart attacks and should not be ignored.
Risk Factors For RCA Blockage
Several factors contribute to the development of coronary artery disease (CAD) leading to a blocked RCA. In Singapore, lifestyle and genetic factors play a significant role. Key risk factors include:
- High Cholesterol Levels: Excess cholesterol in the blood contributes to plaque formation.
- Hypertension (High Blood Pressure): Increases strain on the arteries, leading to damage and blockages.
- Diabetes: Diabetes is a common condition in Singapore that significantly raises the risk of heart disease.
- Smoking: One of the leading causes of heart disease, smoking damages arterial walls and accelerates plaque build-up.
- Sedentary Lifestyle: Lack of physical activity leads to obesity, high cholesterol, and hypertension.
- Family History: If you have close relatives with heart disease, your risk is significantly higher.
Diagnosis And Treatment Options In Singapore
Early diagnosis is crucial in preventing severe complications. In Singapore, advanced cardiac screening and diagnostic tests are widely available, including:
- Electrocardiogram (ECG): Detects abnormal heart rhythms and signs of previous heart attacks.
- Stress Test: Assesses how well the heart functions under physical exertion.
- Coronary Angiography: A specialised X-ray to detect blockages in the arteries.
- Cardiac MRI Or CT Scan: Provides detailed images of the heart and blood vessels.

Treatment Approaches
Treatment depends on the severity of the blockage and overall heart function. In Singapore, top cardiologists offer various treatment options, including:
- Medications: Prescribed to lower cholesterol, reduce blood pressure, and prevent blood clots.
- Angioplasty & Stenting: A minimally invasive procedure where a small balloon is inflated inside the artery to reopen it, followed by the insertion of a stent to keep it open.
- Coronary Artery Bypass Grafting (CABG): A surgical procedure where a healthy blood vessel is used to bypass the blocked artery, restoring blood flow.
- Lifestyle Changes: Patients are advised to adopt a heart-healthy diet, exercise regularly, and quit smoking to prevent further complications.
