Modifiable Risk Factors for Heart Disease: What You Can Control

Risk factors are certain exposures, attributes or characteristics that increase a person's chance of developing a health disorder or condition. More specifically, modifiable risk factors for heart disease are those characteristics that are manageable individually through lifestyle changes or medical treatment.

What are the Risk Factors of Cardiovascular Disease?

Some modifiable risk factors for cardiovascular disease include:

• High cholesterol
• High blood pressure
• Diabetes
• Lack of physical activity
• Obesity
• Unhealthy diet
• Excessive alcohol consumption
• Smoking

By restricting these conditions, a person can greatly minimise their risk of suffering from an abrupt heart attack or other heart-related conditions.

Understanding the Modifiable Risks to Prevent Cardiovascular Disease

Some major risk factors for heart diseases include hypertension/ high blood pressure, obesity, smoking, high cholesterol, family medical history of atherosclerotic cardiovascular disease, etc. Among these risks, there are several factors you can adjust as risk factors, while you cannot control a few of them through lifestyle.

As humans cannot manage some of the most alarming risk factors, it becomes even more vital to manage the conditions that can be modified.

Here's how you can curb the potential of developing cardiovascular disease:

Stop Tobacco Use and Smoking

Tobacco usage can lead to strokes and heart attacks as it forces your heart to beat faster. In addition, smoking damages blood vessels, accelerating atherosclerosis (plaque buildup), which can rupture and trigger clots. 

Thus, if you smoke, you can seek help for quitting. Through nicotine replacement therapies and certain behaviour change programs, you can successfully modify your habits and switch to a better lifestyle.

Induce Daily Physical Activity

Inactive lifestyle habits can slowly increase the chances of developing coronary heart disease. To restrict this, you can incorporate moderate to vigorous physical activities in your routine and reduce heart attack risks.

Moreover, daily workouts can help lower blood cholesterol, weight and sugar levels. In addition, individuals having high blood pressure can benefit from exercising regularly.

Schedule Routine Checkups for Pre-existing Health Conditions

If you have a pre-existing health condition like diabetes, it is crucial to keep your sugar levels within the doctor-recommended range. Thus, regular checkups and medication are important.

Furthermore, you should stick to healthy meals, ensure regular physical activity and control your weight. Doctors can also provide you with medicines to help control your insulin levels.

Additional Factors That May Play a Part in Heart Disease

Besides the controllable factors, here are a few other traits that result in heart disease among humans:

Genetics and Family History

Genetic factors have been found to play a significant role in heart disease, high blood pressure, and similar related conditions. However, doctors have observed that not sharing common environments with other family members can partially minimise the risk.

The risk of developing heritable heart disease can increase further when someone combines unhealthy lifestyle habits with it. It can be eating unhealthy or junk food regularly, or even smoking.

Age and Sex

Heart disease is the most common reason leading to death for both men and women. However, as you age, the risk of developing related illnesses increases.

Race and Ethnicity

A stroke or a sudden heart attack can occur to anyone. However, certain groups have shown higher instances of suffering from heart disease.

For instance, heart disease is the leading cause of death for African Americans, Alaska Natives, and American Indians.

To ensure a long, healthy life free from heart ailments, you should avoid unhealthy lifestyle habits and exercise regularly. As a precautionary measure, you can visit your preferred medical professional for healthcare check-ups regularly.

Stress/Depression 

Chronic Stress: Triggers prolonged release of stress hormones (e.g., cortisol), which increases Inflammation, damages blood vessels, accelerating atherosclerosis. Also blood Pressure due to stress-induced vasoconstriction.

Depression: Lowers medication adherence

Sleep Apnea (OSA) 

Untreated Obstructive Sleep Apnea (OSA) causes:

Increases hypertension: Repeated oxygen drops (hypoxia) strain the cardiovascular system.

Arrhythmias: OSA disrupts heart rhythm (e.g., atrial fibrillation).

Mechanism: Intermittent hypoxia → oxidative stress → endothelial dysfunction.

Air Pollution 

Trigger Inflammation: Promotes plaque formation in arteries.

Acute Effects: Can precipitate heart attacks/strokes within hours of exposure.

Chronic Effects: Long-term exposure increases CVD mortality by 10–30%.
