Angina occurs when an area of the heart muscles volume of oxygen-rich blood is reduced. This deficit causes discomfort or pain, commonly feeling like indigestion, in the chest that may radiate to the upper limbs, neck, jaw and back.
Types
Stable, unstable and variant are the three types of angina. Angina is not a disease, rather a symptom of an underlying heart condition. Each type of angina has different symptoms and treatments.
Stable Angina
Stable angina, also known as exertional angina, occurs when the heart is working harder from physical exertion. The pain is caused by narrowing or clogged arteries and will usually subside after rest or with medication.
Unstable Angina
Unstable angina is serious and life-threatening and may require emergency treatment. It can occur at anytime with or without physical exertion. It is primarily caused by blocked coronary arteries.
Variant Angina
Variant angina is a rare condition that may occur in individuals with or without coronary artery disease. The pain is caused by spasms in the artery walls causing mild blockages. It generally occurs in the evening and relieved with medication.
Prevention
Making healthy lifestyle changes to include diet, exercise, weight control and smoking cessation will reduce the risk of angina. It is also important to control high blood pressure, high cholesterol and diabetes for a healthier heart.
