Chest discomfort, including chest pains and the conscious realization of heartbeats or shortness of breath, is the most common sign of heart danger. If you have a heart attack, you may feel pain, tightness or pressure in your chest. Different people may experience the symptom differently and may express them differently. Chest discomfort usually lasts more than a few minutes and can happen when you exert yourself in physical activity or even at rest.
Heartburn, nausea, indigestion and feeling like vomiting and stomach pain may be possible signs of heart attack, especially in women. Although heart attacks and not the most common cause of heartburn or nausea, they must be kept in mind, mainly when they occur along with other heart symptoms.
Chest pain that originates in the centre of the chest and moves outwards and downwards on the left side of the body towards your arms could potentially signal a heart condition or heart attack.
Although you may experience fainting and dizziness for many reasons, such as heatstroke, poor ventilation, and even a quick change of position or an emotional shock, it is vital to take note when it is accompanied by other symptoms, such as chest discomfort or shortness of breath.
Jaw or throat pains are usually the result of muscular issues or sinus problems. However, having very severe pain in the centre of the chest that spreads upwards to your jaw or throat could be a sign of a heart attack and requires attention.
Loud snoring accompanied by grasping and waking short of breath is a symptom of sleep apnea - a condition that results in a lack of quality sleep and increasing strain on the heart, which can further lead to cardiac problems.

Swelling of body parts, especially the legs, ankle and feet, is a sign known as oedema and can indicate that the heart is unable to pump blood as well as it should.
Persistent dry cough may also be due to conditions such as allergies, asthma, or other conditions that affect your lungs, like COPD or ILD. However, if your dry cough starts producing white or pinkish mucus, it could signal potential heart problems. This usually happens when blood backs up in the lungs.
Fatigue or feeling exhausted quickly is a warning sign of a heart problem. If you experience fatigue after some activity, such as climbing the stairs or carrying something that used to be easy for you earlier, it may signal reduced cardiopulmonary health. Extreme tiredness or unexplained weakness, sometimes lasting days, should be considered severe and is a potential symptom of heart disease, especially for women.
If your heart is beating out of time for more than a few seconds, it is advisable to seek medical advice and understand the cause.
