Here's a straightforward overview of the causes, symptoms, diagnosis, treatment, and prevention of unstable angina, a serious condition characterized by chest pain.
Causes
In unstable angina, limited blood flow to the heart muscle is typically caused by narrowing or blockage of coronary arteries. This can be caused by a variety of factors, including:
-
The buildup of plaque in the coronary arteries, consisting of cholesterol, fatty deposits, and other substances, can lead to unstable angina.
-
Spasms or contractions of the coronary arteries can temporarily reduce blood flow to the heart, resulting in angina symptoms.
-
Unstable angina can be caused by blood clots in the coronary arteries, either caused by ruptured plaque or other factors.
Symptoms
A person suffering from unstable angina may experience the following symptoms:
-
A feeling of pressure, squeezing, tightness, or burning in the chest, often described as "angina," that lasts longer than 15 minutes.
-
Discomfort may radiate to the neck, jaw, shoulders, arms, or back.
-
Breathing difficulty or feeling short of breath, particularly during physical exertion.
-
It is possible to experience nausea, vomiting, lightheadedness, or fatigue in some cases.
Diagnosis
In order to diagnose unstable angina, you must:
-
Symptoms, medical history, risk factors for heart disease, and previous episodes of angina will be discussed with a healthcare provider.
-
Vital signs, heart sounds, and signs of heart disease may be assessed during a thorough physical examination.
-
The electrocardiogram is used to examine the electrical activity of the heart and detect abnormalities, such as ST-segment depression or T-wave inversion, indicative of unstable angina.
-
Tests of the blood can be performed to measure cardiac enzymes, such as troponin, which may be elevated in cases of unstable angina or damage to the heart muscle.
-
To assess the structure and function of the heart and coronary arteries, imaging studies such as coronary angiography, cardiac CT scans, or stress tests may be ordered.
Treatment
There are several treatment options available for unstable angina, including:
-
To relieve chest pain, reduce blood clotting, and improve blood flow to the heart, medications such as nitroglycerin, aspirin, beta-blockers, calcium channel blockers, or antiplatelet drugs may be prescribed.
-
To restore blood flow to the heart, revascularization procedures such as angioplasty with stent placement or coronary artery bypass surgery may be performed.
-
Modifications in lifestyle can reduce the risk of recurrent episodes of unstable angina and improve heart health overall. Examples include quitting smoking, following a heart-healthy diet, exercising regularly, maintaining a healthy weight, and managing stress.
Prevention
The following steps can be taken to prevent unstable angina:
-
Controlling risk factors for heart disease, such as high blood pressure, high cholesterol, diabetes, obesity, and smoking, can reduce the risk of unstable angina.
-
A regular medical check-up can help detect and manage any underlying conditions that contribute to unstable angina, such as high blood pressure, high cholesterol levels, and other cardiovascular risk factors.
-
Maintaining medication adherence can help control symptoms and prevent complications associated with unstable angina.
-
It is important to know the signs and symptoms of unstable angina, seek prompt medical attention in case of chest pain or discomfort, and have emergency contact information handy.
