In addition to pumping blood to various organs, the heart also has its own blood supply, through which it receives its oxygen and nutrient supply. In patients with coronary artery disease and atherosclerosis, there is a narrowing of the blood vessels which reduces the amount of blood flow to the target organs, including the heart.
When this happens in the heart, there is chest pain due to overexertion of the heart muscles. There could be two patterns to this chest pain. With regular exertion like exercise, there would be chest pain, and most patients are familiar with this pattern.
This is known as angina pectoris or stable angina. In some people or in some instances, chest pain occurs which is sudden and not of a predictable pattern. It could be related to extreme exertion or stress. This is known as unstable angina and can lead to heart attack and be life-threatening.
Stable angina or angina pectoris has a stable, predictable pattern which most patients get familiar with over a period of time and learn to manage. Read on to know more about the signs and symptoms and management techniques.
Signs and symptoms: Stable angina usually occurs after a round of physical exertion. The patient feels a feeling of tightness in the chest which feels like the chest being squeezed. The pain can gradually spread to the shoulder, arms and even the neck. The pain can also be induced by eating, exposure to cold, emotional stress. It lasts for about 15 minutes and is relieved by rest and sublingual nitroglycerin. The pain intensity does not change with position or coughing. In addition, the patient may also experience shortness of breath, fatigue, profuse sweating, nausea, and dizziness.
The patient may be able to detect signs on further testing including ECG, echocardiography and stress testing. Features like cardiomegaly, altered ejection fraction would be detected based on the severity of the disease.
Treatment: Immediate treatment to relieve the pain includes resting and sublingual nitroglycerin. On an ongoing basis, the treatment would include 3 approaches – lifestyle changes, medications, and surgery.
- Lifestyle changes: Regular exercise, smoking cessation, reduced fat intake, reduced alcohol consumption, weight loss, and stress management are some lifestyle changes to be made to improve symptoms.
- Medications: A number of medications would be used depending on patient’s symptoms. Aspirin to prevent clotting, medications to control blood pressure and cholesterol and diabetes.
- Surgery: In patients with advanced coronary artery disease, revascularization methods may be required, which includes angioplasty and coronary bypass.
In a person with known risk factors, it is advisable to have regular checkups so that the disease progression can be controlled and symptoms managed with minimal intervention. If you wish to discuss about any specific problem, you can consult a Cardiologist.
