WEB DESK: A heart attack occurs when blood flow to the heart is severely reduced or blocked, often because fatty deposits build up in the arteries. These deposits, known as plaque, can contribute to blood clots that restrict circulation.
Heart attacks can happen suddenly, but some warning signs may appear weeks beforehand. Recognising symptoms and seeking urgent medical care can improve the chances of recovery. World Heart Day is observed on September 29 to raise awareness about cardiovascular disease.
Possible early warning signs
A study involving 515 women found that some experienced symptoms in the month before a heart attack. These included unusual fatigue or weakness, disrupted sleep, shortness of breath and discomfort in the chest.
The Cleveland Clinic also lists chest pressure or tightness, pain in the arms, jaw, neck or back, cold sweats, heartburn-like discomfort, breathing difficulties, nausea or vomiting, and unusual tiredness as possible warning signs. These symptoms do not necessarily mean a person is having a heart attack; a medical professional can assess the cause.
Symptoms can vary
Common heart attack symptoms include chest discomfort or pressure, weakness, fatigue, shortness of breath, dizziness, fainting or confusion. Some people have mild symptoms, while others experience severe pain. A heart attack can also occur without obvious symptoms.
Chest discomfort is the most commonly reported symptom among both men and women. Women may also experience symptoms such as severe pain in the neck, arm or back.
Who may be at greater risk?
A heart attack can affect people of any age or sex. Risk factors include obesity, diabetes, smoking, high blood pressure, high cholesterol and a family history of heart disease. Heart attacks are also being reported more often among people under 40.
Seek emergency medical help if you think you or someone else may be having a heart attack. This article is for general information and is not a substitute for advice from a healthcare professional.
