A heart attack, or myocardial infarction (MI), is permanent damage to the heart muscle. "Myo" means muscle, "cardial" refers to the heart, and "infarction" means death of tissue due to lack of blood supply. There are certain “danger zones” when human heart is likely to suffer an attack. Below are the five major events of our day to day life which may create an imbalance in the blood flow resulting in a cardiac arrest.
During a flu
Along with the extreme exhaustion, achiness and high fever, the flu may multiply the odds of having a heart attack for up to three days following the illness. The virus may trigger an inflammatory response that can damage arteries. Being dehydrated thickens the blood, making it prone to form a clot. A fever can increase your heart rate, forcing the heart to work harder.
A big sporting event
Cheering for your team can be fatal for your heart if you get wrapped up in the game that your emotions spiral out of control. Soccer`s World Cup is serious business in Brazil. When researchers studied data of four world cups, they found that heart attacks increased during the tournament`s finals and rates were highest when Brazil was playing compared to other teams.
A Monday workload
A day-by-day breakdown of the incidence of heart attacks reveals that attacks spike on the days when we return to work after a break. Stress over the coming workweek raises levels of adrenaline and cortisol, which may increase blood pressure and clotting walking at lunch to relieve midday stress is a good idea. Taking meditation sessions also help relieve the stress.
Death of a loved one
Researchers who analyzed thousands of heart attack victims found that those grieving a death were more likely to have an increased heart attack risk in the week following their loved one`s passing. Swedish research found that the heart attack risk remains elevated for several years after the death of an adult sibling. It is important to take counselling sessions after the loss of a near one if the pain still remains stagnant in your mind.
A devastating natural disaster
In the three weeks following the 8.9-magnitude earthquake and accompanying tsunami that killed thousands of people in Japan in 2011, the rate of heart attacks among survivors increased threefold, compared with the rate during the same calendar weeks in past years. It`s important for first responders and health-care providers to be aware of this.
