Introduction:

In India, cardiovascular diseases (CVDs) are a significant public health issue, responsible for a considerable number of deaths each year. Among the various forms of CVDs, unstable angina poses a particular challenge due to  its unpredictable nature and potential for severe complications. This article aims to shed light on unstable angina, its signs and symptoms, risk factors, types, diagnostic tests, treatments, and potential complications in the context of India, using simple and easy-to-understand language.

Signs and Symptoms:

Unstable angina is a type of chest pain that occurs when the blood flow to the heart is restricted, resulting in inadequate oxygen supply to the heart muscle. The most common symptom of unstable angina is chest discomfort or pain, which may feel like a squeezing, pressure, or heaviness. However, it is important to note that chest pain alone may not always be present in unstable angina. Other symptoms can include shortness of breath, fatigue, sweating, nausea, and lightheadedness.

What is Unstable Angina? :

Unstable angina, also known as acute coronary syndrome (ACS), is a form of angina pectoris that presents an increased risk of a heart attack. It is characterized by chest pain that occurs at rest or with minimal exertion, and the pain may be more severe and prolonged compared to stable angina. Unstable angina is considered a medical emergency, as it signifies an imminent threat to the heart’s blood supply and requires immediate medical attention. 

How is Unstable Angina Diagnosed? :

To diagnose unstable angina, doctors employ various diagnostic tests to assess the condition of the heart and determine appropriate treatment options. Some common diagnostic tests used in India include:

•  Electrocardiogram (ECG): An ECG records the electrical activity of the heart and can help identify abnormal heart rhythms, blockages, or damage to the heart muscle.
•  Cardiac Enzyme Tests: These blood tests measure the levels of certain enzymes, such as troponin, in the blood. Elevated levels of these enzymes can indicate heart muscle damage, suggesting unstable angina or a heart attack.
•  Stress Testing: Stress tests evaluate how the heart performs under physical stress. It can involve exercising on a treadmill or receiving medications that simulate the effects of exercise on the heart. Changes in the ECG during stress testing can provide valuable insights into the heart’s condition.
•  Coronary Angiography: This invasive procedure involves injecting a contrast dye into the coronary arteries, followed by X-ray imaging. It helps visualize any blockages or narrowing of the arteries, guiding further treatment decisions.

Treatment Options for Unstable Angina:

Once diagnosed, the management of unstable angina primarily focuses on stabilizing the condition, relieving symptoms, and reducing the risk of complications. Treatments commonly used in India include:

•  Medications: Nitroglycerin is often prescribed to relieve chest pain by relaxing and widening blood vessels. Aspirin and other antiplatelet medications may be prescribed to prevent blood clots. Additionally, beta-blockers, calcium channel blockers, and statins may be recommended to control blood pressure, reduce heart rate, and manage cholesterol levels.
•  Angioplasty and Stenting: In cases where significant blockages are identified through coronary angiography, angioplasty may be performed. This procedure involves inserting a balloon-tipped catheter into the blocked artery and inflating it to widen the artery. A stent, a small mesh tube, may also be placed to keep the artery open.
•  Coronary Artery Bypass Grafting (CABG): CABG surgery may be recommended for individuals with severe blockages in multiple coronary arteries. It involves bypassing the blocked arteries using blood vessels from other parts of the body, restoring blood flow to the heart.

 Complications of Unstable Angina:

Unstable angina poses several potential complications, including:

• Heart Attack: Unstable angina carries a high risk of progressing to a heart attack, where a complete blockage of a coronary artery occurs, leading to significant damage to the heart muscle.
•  Heart Failure: Severe and prolonged episodes of unstable angina can weaken the heart muscle and impair its ability to pump blood effectively, resulting in heart failure.
•  Arrhythmias: Disturbances in the heart’s electrical system can cause irregular heart rhythms (arrhythmias), which can be life-threatening if not promptly addressed.
• Death: If left untreated or if complications arise, unstable angina can result in cardiac arrest or sudden death.

Unstable angina is a critical cardiovascular condition characterized by chest pain or discomfort caused by reduced blood flow to the heart. Prompt and effective management is essential to prevent potentially life-threatening outcomes such as heart attacks.
