Al-Marsad Newspaper: Experts have revealed subtle signs that appear months, or even longer, before a heart attack.
“The majority” of heart attacks show typical symptoms such as angina (chest pain), heart palpitations, shortness of breath and cold sweats, said Dr Zi Jian Xu of Sutter Health.
He pointed to six other “atypical symptoms” of the fatal event, and they include fatigue, a vague feeling of uneasiness, vague discomfort, abdominal pain, back pain, and a general decrease in stamina, indicating that some people have a number of these groups of symptoms since “. months” or “even longer before the heart attack.
Dr. Shaw explains: A heart attack is preceded by injury to the coronary artery, and in this case, the artery narrows over time. And when the artery narrows to more than 70%, warning symptoms will begin to appear early, especially with physical exertion.
Coronary artery disease is usually caused by high levels of “bad” cholesterol in the blood, and this may cause a heart attack months or even years after coronary artery disease.
Heart attacks can also occur because the heart does not receive enough oxygen even though the blood vessels are not completely blocked. Iron deficiency is known to increase the risk of heart attack.
Iron is used to make red blood cells that carry oxygen to all cells of the body. And when levels are low, so are red blood cell levels. Hypoxia is another cause of a heart attack.
