The heart attack
more properly called myocardial infarction – is a pathological process by which the flow of blood to the myocardium (ie the heart muscle) is inadequate to the demands.
some most common symptoms are Chest Discomfort,Nausea, Indigestion, Heartburn, or Stomach Pain,
Often caused by atherosclerosis, this severe condition determines the necrosis (ie death) of the myocardial tissue and a reduction in the contractile capacity of the heart.
According to some recent studies, episodes of heart attack would be more frequent in the morning and in particular between 8 and 9 meridian wings.
What is the scientific explanation of all this?
The researchers observed that, in the morning, the levels of cortisol – a hormone secreted by the adrenal glands and essential for life – are higher than at other times of the day. High amounts of cortisol cause an increase in various vital parameters, including blood pressure.
The latter, as is known, when it is at high levels (hypertension) is one of the most important factors favoring the rupture of any atheromatous plaques present inside the coronary arteries.
According to the studies in question, the concentration of cortisol would reach its peak between 8 and 9 am and this would explain why many episodes of myocardial infarction occur during this time.
