Differences between cardiac arrhythmia, atherosclerosis, angina, myocardial infarction and hypertension?
I learned cardiovascular disease in class and seem to be confused … symptoms and how they developed .. that seem very similar … How do I differentiate them? anwers that are easy understand fully appreciated. The question is not complete .. is that? .. That is, the differences between the cardiac arrhythmia, atherosclerosis, angina pectoris, myocardial infacrtion and hypertension.
When I was learning about the heart, helped me think of it as a car engine. The cars have electrical systems to fire the fuel injectors. The moment when the heart is electric and when fired, produces mechanical results. When your car runs rough, time is off, and uses a lot of fuel. The heart is in the same way. When the timing is off, the camera is not filled, and when they contract (beat) not move a lot of blood. But the heart keeps doing the same amount of work! People with arrhythmias, have less energy, can be pale, and shortness of breath. Atherosclerosis is like clogging fuel injectors. When arteries become clogged with plaque, the fuel (oxygen and energy) can not reach to places that need it. Infarction means the death of cells. Fortunately, when their car dies from poor fuel delivery,,,, the engine is not in ruins. When parts of your heart are deprived of oxygen, cells die. Most times, a myocardial infarction (heart attack) does not ruins the whole heart. Only becomes weaker. But unlike your car, the heart walls can not be repaired. Hypertension is when the pressure in arteries is more than 120/70. When the heart beats, it has to force the opening of the aortic valve to obtain blood for the rest of your body. If the pressure on the other side of the valve is high, the heart must work much harder. When a muscle works harder, becomes larger. If you is a man on the beach, the large muscles are a plus. But a big heart is a muscle problem. When the heart muscle gets bigger, the cameras smaller. Therefore, the heart pumps less blood with each beat. But, being larger, it requires more energy and oxygen to do so. People with enlarged hearts have little resistance and are at risk of a heart attack. Remember clogged arteries? Now that the heart is larger, it takes more —- arterial blood cannot quite reduced and the supply and the heart tissue dies. Good luck with your studies!
