Heart Disease

Updated: Jun 20, 2022

Why Do So Many People Die From Cardiovascular / Heart Disease?

Heart disease still remains as number one killer all over the world even though medical advances have made it so that many more people can survive heart attacks. According to the Ministry of Health, heart disease is Malaysia's largest cause of death, with smokers and those who live a sedentary lifestyle among the high-risk groups.

A sedentary lifestyle refers to a lifestyle with a lot of sitting and lying down and very little to no workout. This is too dangerous for your heart.

Heart disease is a term that encompasses a wide range of heart problems. It not only refers to problems in the heart but also problems in the blood vessels. This is because the two are interrelated and will affect each other in case any problems occur. This is due to the cardiovascular system connecting the heart and all the organs in the body. Heart problems can also affect other organs such as the brain, kidneys, and liver.

Do you ever hear anyone around you die suddenly and it comes out because of cardiac arrest?

This is called Sudden Cardiac Death (SCD) which means is sudden, unexpected death caused by loss of heart function. This occurs most frequently in adults in their mid-30s to mid-40s and affects men twice as often as it does women.

A heart attack is not sudden cardiac arrest (myocardial infarction). A heart attack occurs when one or more coronary arteries get blocked (coronary heart disease), preventing the heart from receiving enough oxygen-rich blood. The heart is harmed when oxygen in the circulation cannot reach the heart muscle.

Sudden cardiac arrest, on the other hand, occurs when the heart's electrical mechanism fails and becomes extremely erratic. The heart is racing at a dangerously high rate. Ventricular fibrillation occurs when the ventricles flutter or quiver, and blood is not supplied to the body.

This is happening sometimes due to undiagnosed heart conditions such as genetic heart disease. The undetected heart problem may cause a young person to suddenly die during physical activities. This is made worse if you are a smoker and do not follow a balanced diet.

Other types of heart diseases became the number one killer among Malaysians :

-Coronary heart disease (Coronary artery disease)

-Heart failure

-Arrhythmia (Atrial Fibrillation)

-Valve disease

-Myocardial disease

-Pericardial disease

-Congenital heart disease


-Vascular disease & Stroke

The most important behavioral risk factors for heart disease are :

Behavioral risk factors for heart disease

The effects of behavioral risk factors may show up in individuals as raised blood pressure, raised blood glucose, raised blood lipids, and overweight and obesity. These “intermediate-risk factors” can be measured in primary care facilities and indicate an increased risk of heart attack, stroke, heart failure, and other complications.

Tobacco cessation, salt reduction in the diet, increased fruit and vegetable consumption, regular physical activity, and avoidance of problematic alcohol use have all been demonstrated to lessen the risk of cardiovascular disease. Health policies that create environments that make healthy options affordable and accessible are critical for encouraging people to develop and maintain healthy habits.

In addition, drug treatment for hypertension, diabetes, and high blood lipids is necessary to reduce cardiovascular risk and prevent heart attacks and strokes among people with these conditions.

The only way to prevent this heart disease is with regular medical checkups and early heart screening. This can help to detect those heart problems in early-stage and can be treated before it's too late.
