Heart Diseases
Heart disease is the leading cause of death in the United States, encompassing various conditions that affect the heart's structure and function.
Overview
Heart disease is a general term for cardiovascular disease, which involves the heart and blood vessels. While some forms are congenital, others develop over a lifetime due to various factors.
Common Types
Coronary artery disease is the most prevalent type, caused by plaque buildup that restricts blood flow. This can lead to:
- Angina: Chest pain from lack of blood flow.
- Heart attacks: Death of heart muscle due to loss of blood flow.
- Heart failure: The heart's inability to pump enough blood.
- Arrhythmia: Irregular heart rate or rhythm.
Other types include conditions affecting heart valves or the heart muscle (cardiomyopathy).
Risk Factors
Risk factors are categorized into those that can be changed and those that cannot:
- Non-modifiable: Age, sex, family history/genetics, and race/ethnicity.
- Lifestyle habits: Diets high in saturated fats/salt, physical inactivity, alcohol consumption, smoking, and stress.
- Medical conditions: High blood pressure, high cholesterol, diabetes, obesity, autoimmune/inflammatory diseases, chronic kidney disease, and metabolic syndrome.
Diagnosis and Treatment
Diagnosis involves a review of medical history and family health history, a physical exam, and various heart and blood tests. A cardiologist may be consulted for specialized care.
Treatment plans are tailored to the specific type and severity of the disease and may include:
- Heart-healthy lifestyle changes.
- Medicines.
- Procedures or surgeries.
- Cardiac rehabilitation.
