Angina pectoris, commonly referred to as angina, is a condition characterized by chest pain or discomfort that occurs when the heart muscle does not receive enough oxygen-rich blood. This condition is a symptom of coronary artery disease, which is a leading cause of death worldwide.
The term "angina" is derived from the Latin word for "choking," which accurately describes the sensation of chest pain experienced by individuals with this condition. Angina pectoris is not a disease itself, but rather a symptom of an underlying cardiovascular condition.
In this article, we will delve into the causes and symptoms of angina pectoris, as well as the factors that increase the risk of developing this condition.
Causes of Angina Pectoris
Angina pectoris occurs when the heart muscle does not receive enough oxygen-rich blood, which is usually caused by a reduction in blood flow to the heart. This reduction in blood flow is often the result of one or more of the following factors:
- Coronary artery disease: The coronary arteries, which supply blood to the heart, become narrowed or blocked due to a buildup of plaque, a substance composed of fat, cholesterol, and other substances.
- Blood clots: A blood clot forms in one of the coronary arteries, blocking the flow of blood to the heart.
- Cardiac arrhythmias: Abnormal heart rhythms, such as atrial fibrillation, can reduce the heart's ability to pump blood effectively.
- Heart failure: The heart becomes weakened and is unable to pump enough blood to meet the body's needs.
- Anemia: A reduction in red blood cells or hemoglobin in the blood can reduce the amount of oxygen delivered to the heart muscle.
- Carbon monoxide poisoning: Exposure to carbon monoxide can reduce the amount of oxygen delivered to the heart muscle.
Risk Factors for Angina Pectoris
Several factors can increase the risk of developing angina pectoris, including:
- Age: Men over 45 and women over 55 are at increased risk.
- Family history: A family history of heart disease or angina pectoris increases the risk.
- High blood pressure: Uncontrolled high blood pressure can increase the risk.
- High cholesterol: High levels of low-density lipoprotein (LDL) cholesterol can increase the risk.
- Smoking: Smoking damages the coronary arteries and increases the risk.
- Diabetes: Uncontrolled diabetes can increase the risk.
- Obesity: Excess weight can increase the risk.
Symptoms of Angina Pectoris
The symptoms of angina pectoris can vary from person to person, but typically include:
- Chest pain or discomfort: A feeling of pressure, tightness, or squeezing in the chest that may radiate to the arms, back, neck, jaw, or throat.
- Shortness of breath: Difficulty breathing or feeling winded even when at rest.
- Fatigue: Feeling weak or tired, even after resting.
- Pain or discomfort in the arms, back, neck, jaw, or throat: Pain or discomfort in these areas can be a sign of angina pectoris.
Types of Angina Pectoris
There are two main types of angina pectoris:
- Stable angina: This type of angina occurs when the heart muscle does not receive enough oxygen-rich blood during physical activity or stress.
- Unstable angina: This type of angina occurs when the heart muscle does not receive enough oxygen-rich blood at rest or with minimal physical activity.
Diagnosis and Treatment of Angina Pectoris
Diagnosing angina pectoris typically involves a combination of the following:
- Medical history: A thorough medical history to identify risk factors and symptoms.
- Physical examination: A physical examination to check for signs of heart disease.
- Electrocardiogram (ECG or EKG): An ECG or EKG to check for abnormal heart rhythms.
- Stress test: A stress test to check for signs of heart disease during physical activity.
- Coronary angiogram: A coronary angiogram to check for blockages in the coronary arteries.
Treatment for angina pectoris typically involves a combination of the following:
- Lifestyle changes: Making lifestyle changes, such as quitting smoking, exercising regularly, and eating a healthy diet.
- Medications: Taking medications, such as nitrates, beta blockers, and statins, to help manage symptoms and reduce the risk of heart attack.
- Coronary artery bypass grafting (CABG): Undergoing CABG surgery to bypass blocked coronary arteries.
- Percutaneous coronary intervention (PCI): Undergoing PCI, also known as angioplasty, to open blocked coronary arteries.
