Overview of Cardiovascular Disease Risk Factors and Causes

Cardiovascular disease (CVD) is one of the leading causes of death in the world. It is responsible for around 17.3 million deaths globally each year, making up 31% of all global deaths. It can present itself in a variety of ways, including heart attacks, stroke, chest pain, and high blood pressure. Although we understand what CVD is and how it can affect us, there are still many unanswered questions about its causes and risk factors. In this article, we’ll explore these causes and risk factors, and provide an overview of preventive practices to help reduce the risk of acquiring the disease.

What Causes Cardiovascular Disease?

The exact cause of cardiovascular disease is unknown, however, certain lifestyle habits and medical conditions can increase the risk of developing the condition. The most common causes of cardiovascular disease are high blood pressure, smoking, high cholesterol, diabetes, stress, and a sedentary lifestyle. All of these have direct impacts on a person’s heart, as well as their overall health.

High Blood Pressure

High blood pressure, or hypertension, is thought to be responsible for around 10 million deaths each year. It is caused when the pressure of the arterial walls is higher than it should be, which forces the heart to work harder in order to pump blood through the body. This extra strain can lead to the hardening and narrowing of the arteries, as well as an increased risk of heart attack and stroke.

Smoking

Smoking can also increase the risk of CVD. It increases the amount of carbon monoxide and nicotine in the blood, both of which constrict the arteries and make it more difficult for blood to reach the heart muscle. Smoking can also lead to the formation of fatty deposits in the arteries, which can reduce the flow of blood to the heart muscle. All of these combined increase the risk of a heart attack or stroke.

High Cholesterol

High cholesterol is a major risk factor for CVD. It is caused by an imbalance in the amount of fats (lipids) in the body. When the body has too much lipids, they accumulate in the arteries and form thick deposits, called plaques. These can narrow or block the arteries, preventing the heart from receiving enough blood and oxygen, which can lead to a heart attack or a stroke.

Diabetes

Diabetes is another risk factor for CVD. It is a metabolic disorder in which the body can’t properly use the glucose from food, leading to high levels of glucose in the blood. This in turn causes an increased risk of artery damage, which can lead to an increased risk of heart attack and stroke.

Stress

Chronic stress can also increase the risk of CVD. Stress causes an increase in certain hormones in the body, such as adrenaline and cortisol. This puts extra strain on the heart, which can lead to an increased risk of heart attack and stroke.

A Sedentary Lifestyle

A sedentary lifestyle is one of the most common risk factors for CVD. It can lead to a decline in cardiovascular health, due to reduced levels of physical activity and inadequate nutrition. A lack of physical activity can also cause cholesterol levels to rise, as well as an increased risk of other conditions like obesity and diabetes, both of which increase the risk of CVD.

What Can I Do To Prevent CVD?

The most important way to reduce your risk of CVD is to make healthy lifestyle changes and be aware of the risk factors. Here are some tips to help you stay healthy and reduce your risk of CVD.

Eat a Healthy Diet

A healthy diet can help you maintain a healthy weight, prevent diabetes, and reduce cholesterol. Be sure to include foods such as fresh fruits and vegetables, whole-grain carbohydrates, and lean proteins. Avoid processed and refined foods, as well as foods high in saturated fat and sugar.

Maintain a Healthy Weight

Being overweight or obese increases the risk of CVD. By maintaining a healthy weight, you can reduce the strain on your heart and reduce your chances of developing an unhealthy condition.

Exercise Regularly

Regular physical activity is essential for maintaining a healthy heart. Aim for 150 minutes of moderate-intensity exercise per week, such as walking, cycling, swimming, or jogging. You can also do strength training exercises two to three times per week. This will help strengthen your heart and reduce your risk of CVD.

Quit Smoking

If you smoke, quitting is the most important thing you can do to reduce your risk of CVD. There are many resources available to help you quit, including support groups, counseling, and medications. Speak to your doctor to find out which resources are best for you.

Avoid Stress and Get Enough Sleep

Stress can significantly increase your risk of CVD, so be sure to take time to relax and get enough sleep. Aim for seven to eight hours of sleep each night, and make time for activities that you enjoy. This will help you stay relaxed and reduce your risk of CVD.

Conclusion

Cardiovascular disease is a serious condition that affects millions of people worldwide. Although the exact cause of CVD is unknown, certain lifestyle habits and medical conditions can increase the risk. To reduce your risk of CVD, it is essential to make healthy lifestyle changes such as eating a healthy diet, maintaining a healthy weight, exercising regularly, quitting smoking, avoiding stress, and getting enough sleep. By following these preventative practices, you can significantly reduce your risk of acquiring the disease.
