A key aspect of good overall health is optimal cardiovascular health, as the heart plays a key role in transporting oxygen, blood, and other key nutrients to other body parts, allowing them to carry out vital functions. However, heart diseases like arrhythmia, cardiomyopathy, and coronary artery disease can cause problems in the structure and function of the heart. Here, it is important to recognize the following warning signs of heart disease and seek timely intervention:

1. Excessive sweating
It is common to sweat in hot weather or after engaging in physical activities. However, sweating without any apparent reason can be a cause for concern. Further, if sweating is accompanied by chest pains, one should seek immediate medical attention.

2. Chest discomfort or pain
A blockage in the arteries can cause tightness and heaviness in the chest. The symptom may indicate a heart attack. Additionally, if the pain is irregular and occurs while doing exercise or any physical activity and ceases when that activity is withdrawn, then it might be a sign of angina—reduced blood flow to the heart. Sometimes, the pain can extend to the neck and jaw.

3. Leg pain
The initial signs of peripheral artery disease (PAD) are pain and cramps in the legs, especially if the symptom worsens while taking a walk or engaging in other physical activities. PAD is associated with blood vessels narrowing or experiencing plaque buildup, leading to poor blood circulation. Here, the tissues are deprived of oxygen, causing pain. The condition is common in those who smoke and have diabetes.

4. Indigestion
Sometimes, one may experience indigestion and a burning sensation along the chest and stomach when experiencing a heart attack. While heartburn can develop due to acid reflux, if one is at risk of heart disease, they should avoid ignoring this symptom and get it examined by a doctor as soon as possible.

5. Pain in the left arm
Chest pain that seems to spread along the left arm is a common sign of a heart attack. Sometimes, the pain may be limited to the left arm. This symptom should prompt one to seek medical intervention.

6. Swelling in the ankles
A cardiovascular system that is not working optimally can cause poor blood circulation and a buildup of fluid in the legs and ankles. This can also be a sign of heart failure.

7. Abnormal heart rate
Rapid heartbeat is common with excitement or fear, but a sudden increase in heart rate, especially when accompanied by palpitations, chest pressure, or breathlessness, can be a sign of a cardiovascular issue.

8. Dizziness
Passing out for a moment or feeling lightheaded can be a sign of a heart-related issue. It is typically brought on by the heart being unable to pump enough blood.

9. Feeling unwell or uneasy
Feelings of uneasiness and nausea, especially if accompanied by bouts of chest pain while just sitting or lying down, can be signs of heart disease. One should consult a doctor to seek a proper diagnosis and prevent further complications.

It is important to consult a doctor upon experiencing any of the abovementioned signs.
