Heart Disease
What is heart disease?
Heart disease encompasses various conditions impacting the heart such as coronary artery disease (insufficient oxygen supply to the heart), cardiovascular disease (affecting both blood vessels and heart muscle) and acute coronary syndrome (sudden reduction in blood flow to the heart).
Causes
Heart disease is influenced by a combination of factors including aging, genetics and lifestyle choices.
- Ageing: As people age the heart undergoes structural and functional changes such as thickening of the heart walls, decreased elasticity of blood vessels and impaired heart muscle function, increasing the risk of developing cardiovascular conditions.
- Genetics: Inherited conditions such as familial hypercholesterolemia, familial dilated cardiomyopathy and familial hypertension can significantly elevate the risk of developing heart disease at a younger age even in the absence of traditional factors.
- Lifestyle choices: Unhealthy behaviours such as smoking, physical inactivity, excessive alcohol consumption, chronic stress and poor dietary habits high in saturated fats, cholesterol and sodium contribute to the development and progression of cardiovascular conditions.
Symptoms
- High blood pressure (hypertension)
- Chest pain (angina)
- Feeling light-headed
- Nausea
- Cold sweats
- Pain in the arms or shoulders
- Shortness of breath
- Coronary artery disease
- Heart rhythm problems (arrhythmia)
- Heart valve disease
- Aortic stenosis (narrowing of the aortic valve)
- Atherosclerosis (narrowing or hardening of the heart’s arteries)
- Stroke
If you are experiencing chest pain, shortness of breath, or bouts of fainting, call 000 and seek emergency medical care as soon as possible.
Preventing heart disease
Prevention involves a proactive approach that addresses various risk factors and promotes heart-healthy habits throughout life. Here are some key strategies:
Treatment
Treating heart disease often involves multiple methods, including lifestyle changes, medications and in some cases surgical interventions.
Lifestyle changes
Adopting heart-healthy habits can significantly improve heart health and manage heart diseases. This includes maintaining a balanced diet low in saturated fats, cholesterol and sodium, while high in fruits, vegetables, whole grains and lean proteins. Regular physical activity such as aerobic exercise and strength training helps to control weight, lower blood pressure and improve overall cardiovascular function. Smoking cessation and limiting alcohol consumption are also crucial lifestyle modifications.
Medications
Various medications may be prescribed to manage heart disease and its risk factors. These may include:
Surgery
In cases where lifestyle changes and medications are insufficient, surgical interventions or minimally invasive procedures may be necessary.
- Coronary angioplastyÂ
- Coronary artery bypass graft
- Pacemakers
- Advanced heart failure therapies such as heart transplant
