40% Blockage Of Right Coronary Artery – Here’s What You Should Do

A 40% blockage of the right coronary artery (RCA) is an early-stage heart condition that can progress into a more serious problem if left untreated. While it may not cause immediate symptoms or require emergency treatment, it is a clear warning sign that your heart health needs attention.

In Singapore, heart disease remains one of the leading causes of death, with coronary artery disease (CAD) being a major contributor. If you have been diagnosed with an RCA blockage, consulting a qualified cardiologist in Singapore is crucial to managing your risk and preventing further complications.

Understanding A 40% Blockage Of The Right Coronary Artery

The right coronary artery (RCA) supplies oxygen-rich blood to the heart, ensuring it functions properly. When plaque made up of cholesterol, fats, and other substances builds up in the artery walls, it narrows the passageway, reducing blood flow.

At 40% blockage, the artery is partially restricted but not completely blocked. While it may not always cause symptoms, it increases the risk of further narrowing, which could lead to angina (chest pain), heart attacks, or heart failure in the future.

Symptoms Of A 40% RCA Blockage

In many cases, a 40% blockage does not cause noticeable symptoms. However, some individuals may experience mild discomfort, especially during physical exertion. Common symptoms include:

• Mild Chest Discomfort Or Tightness – A dull or slight pressure in the chest, especially after exercise.
• Shortness Of Breath – Feeling out of breath after minimal activity.
• Fatigue – Persistent tiredness or lack of energy.
• Dizziness Or Lightheadedness – A sign that your heart may not be pumping blood efficiently.

Even if you feel well, a partial blockage can progress over time, leading to severe complications. Early intervention is key to protecting your heart.

Risk Factors That Increase The Progression Of RCA Blockage

Certain lifestyle and medical factors can accelerate the narrowing of the arteries, increasing the risk of a more severe blockage. In Singapore, the following factors are commonly associated with coronary artery disease:

• High Cholesterol Levels – Excess cholesterol contributes to plaque formation.
• Hypertension (High Blood Pressure) – Puts extra strain on the artery walls.
• Diabetes – A major risk factor among Singaporeans that increases the likelihood of heart disease.
• Smoking – Damages blood vessels and accelerates plaque build-up.
• Sedentary Lifestyle – Lack of exercise contributes to weight gain and poor heart health.
• Unhealthy Diet – Diets high in processed foods, sugar, and unhealthy fats promote arterial blockages.
• Family History – A genetic predisposition to heart disease increases your risk.

What Should You Do If You Have A 40% Blockage Of Right Coronary Artery?

If you have been diagnosed with a 40% blockage, it is important to take proactive steps to manage your condition. Although immediate surgery may not be required, a cardiologist in Singapore can help you implement a personalised treatment and prevention plan.

1. Undergo Regular Heart Screenings

Routine check-ups allow cardiologists to monitor your condition and detect any progression of the blockage. Common diagnostic tests include:

• Electrocardiogram (ECG) – Detects abnormal heart rhythms.
• Stress Test – Evaluates how your heart functions under physical exertion.
• CT Coronary Angiography – Provides a detailed image of the coronary arteries.
• Lipid Profile Test – Measures cholesterol levels to assess heart disease risk.

2. Adopt A Heart-Healthy Diet

Eating a balanced diet is one of the most effective ways to slow the progression of artery blockages. A heart-healthy diet includes:

• Fruits And Vegetables – Rich in antioxidants and fibre to support heart health.
• Whole Grains – Oats, brown rice, and whole wheat products help lower cholesterol.
• Healthy Fats – Avocados, nuts, and olive oil provide beneficial unsaturated fats.
• Lean Proteins – Fish, skinless poultry, and plant-based proteins improve cardiovascular health.

3. Exercise Regularly

Regular physical activity improves blood circulation and prevents further arterial narrowing. Aim for:

• At Least 150 Minutes Of Moderate Exercise Per Week – Activities such as brisk walking, cycling, or swimming.
• Strength Training Twice A Week – Helps maintain muscle mass and supports heart function.

4. Manage Blood Pressure, Cholesterol, And Diabetes

Uncontrolled blood pressure, high cholesterol, and diabetes increase the risk of further blockages. A cardiologist in Singapore may prescribe medications to help regulate these conditions, including:

• Statins – To lower cholesterol.
• Beta-Blockers – To reduce blood pressure and strain on the heart.
• Aspirin Or Blood Thinners – To prevent clot formation.

5. Quit Smoking And Reduce Alcohol Intake

Smoking significantly accelerates plaque build-up in the arteries, increasing the risk of heart attacks. If you smoke, quitting is one of the best things you can do for your heart. Similarly, limiting alcohol intake can help maintain healthy blood pressure levels.

When Should You See A Cardiologist?

Even though a 40% blockage is not a complete obstruction, it should not be ignored. Early management with the help of a cardiologist in Singapore can prevent further complications and improve your quality of life.
