A Vital Step Towards Heart Health
Cardiovascular disease (CVD) is a general term for conditions affecting the heart or blood vessels. CVD is usually associated with a build-up of fatty deposits inside the arteries (atherosclerosis) and an increased risk of blood clots.
CVD remains one of the leading causes of death globally. Despite advances in medical technology and awareness campaigns, the prevalence of CVD continues to increase, so it is a positive step to be aware of the condition and its associated risks. Understanding risk factors and prevention measures offers an opportunity to take proactive steps to protect your heart health and live a longer, healthier life.
The Prevalence of Cardiovascular Disease
Cardiovascular disease encompasses a range of conditions affecting the heart and blood vessels, including coronary artery disease, heart failure, stroke, and hypertension. The World Health Organisation (WHO) estimates that CVD is responsible for 17.9 million deaths annually across the globe, accounting for over 31% of all deaths.
Understanding the Causes
Understanding the causes of cardiovascular disease is the first step towards prevention. Most cases of CVD are attributed to atherosclerosis, a condition characterised by plaque accumulation in the arteries, restricting blood flow to the heart and other organs. Atherosclerosis is influenced by several factors, including a sedentary lifestyle, poor dietary habits, smoking, and obesity.
Risk Factors
Numerous risk factors contribute to the development of cardiovascular disease, some of which can be modified or controlled. These include:
High Blood Pressure (Hypertension): High blood pressure for a sustained period adds strain to the heart and blood vessels, increasing the risk of heart disease and stroke.
High Cholesterol Levels: Elevated LDL cholesterol (often called "bad cholesterol") can lead to plaque build-up in the arteries.
Diabetes: High blood glucose from diabetes can damage blood vessels and the nerves that control the heart and blood vessels. Over time, this damage can lead to heart disease.
Smoking: Tobacco use is a significant risk factor for cardiovascular disease as it damages the blood vessels and reduces oxygen supply to the heart.
Obesity: Excess body weight strains the heart and increases the likelihood of related conditions, such as hypertension and diabetes.
Sedentary Lifestyle: Lack of regular physical activity contributes to obesity and poor cardiovascular health.
Family History: A family history of heart disease can increase the risk of developing CVD.
The Benefits of Understanding Cardiovascular Disease
Empowerment: Awareness of cardiovascular disease symptoms allows you to recognise potential warning signs and seek medical attention when required. Early detection and prompt action can prevent the progression of the disease and improve treatment outcomes.
Lifestyle Modification: Understanding cardiovascular disease risk factors enables you to make informed lifestyle decisions. Lifestyle modifications such as adopting a heart-healthy diet, a regular exercise regime, and quitting smoking, can significantly reduce your risk of developing CVD.
Prevention: By understanding the causes and risk factors, you can take proactive steps to prevent the onset of cardiovascular disease.
Improved Compliance: As an informed individual, you are more likely to adhere to lifestyle changes and medical advice, leading to better disease management and outcomes.
Conclusion
Cardiovascular disease is one of the most significant conditions associated with premature death. Genetic risk factors cannot be directly controlled but the good news is you can manage risk factors in your lifestyle that may help prevent cardiovascular disease. Elevated blood pressure, high cholesterol and the ratio of HDL and LDL cholesterol are all numbers to be aware of as potential contributing factors in developing cardiovascular disease.
