Cold sweats.
Poor circulation can lead to cold sweats and be a symptom of an impending heart attack. If you feel cold and generally unwell, consult your doctor.
Pain in the chest, arms, shoulders and back.
Chest pain is probably one of the most common symptoms of a heart attack. Shoulder, back, and arm pain can also indicate an increased risk of a heart attack, so these factors should be considered as well. Chest pain and pressure occur only a few hours before a heart attack, but there is still time to call an ambulance.
Cold or flu symptoms.
This symptom can be a bit confusing, but it’s worth remembering that many people who have had a heart attack report flu-like symptoms about a month before the unfortunate event. This doesn’t mean that if you have flu-like symptoms, you’re at risk of a heart attack, but you should consult your doctor to be on the safe side.
Constant feeling of tiredness.
If you experience constant fatigue and muscle weakness, you should see a doctor immediately, as there’s a 99% chance you’re having a heart attack. These symptoms are likely the result of poor circulation and typically occur in people who are overweight or obese.
The fatigue you feel is caused by your heart working hard to oxygenate all parts of your body to deliver essential blood. The heavier you are, the harder it is for your heart to pump blood.
Dyspnoea.
Shortness of breath is also a serious warning sign of potential heart failure. Like every other organ in the human body, the lungs require a large amount of oxygen to function properly. Oxygen reaches the lungs via red blood cells. Therefore, poor blood flow to the lungs means difficulty breathing and so on.
Additional warning signs of heart failure:
Nausea
Abdominal pain
Indigestion
