Heart Attack Is The Most Common Type Of Cardiovascular Condition
Other Conditions Are Arrhythmia, And Irregular Heartbeat, And Coronary Heart Disease, A Narrowing Of The Coronary Arteries
According to the CDC, 25% of deaths in the U.S. are caused by cardiovascular conditions. Even though the most known type is a heart attack, there are other conditions. Among them are arrhythmia, in which the heart rate is irregular due to malfunctions in the electrical signals. This can occur when the heart rate is too fast, more than 100 heats per minute (bpm), called tachycardia, or when it is too slow, less than 50 bpm, called bradycardia. However, slow heart rhythm is an indication of good health in endurance and elite athletes, which can lower it up to 40 bpm. Another type of condition is coronary heart disease, in which the coronary arteries, responsible for the blood blow to the heart, narrow due to cholesterol buildup. Heart attack, also known as myocardial infarction, occurs when there is an interruption of the blood flow to the heart, resulting in damage to the heart muscle. Usual symptoms are pressure in the chest and pain in the left arm, but in 20% of the cases, there are no symptoms. It has a mortality rate is 14%. While heart attacks are related to an interruption in the blood flow, cardiac arrests are caused by an interruption or a disorder of the electrical signals that control heartbeat, which is more dangerous, resulting in a mortality rate of 89%. Heart failure is a progressive deterioration of the pumping efficiency. More info click here.
