Heart disease awareness quiz – WRONG STATEMENT: a) Heart attack and cardiac arrest are the same
Heart attack and cardiac arrest are not the same. Heart attack means damage to a region of heart muscle due to sudden blockage in a blood vessel to the region. It can be complicated by a cardiac arrest occasionally. Cardiac arrest is sudden stoppage of the heart and is due to an abnormality in the electrical activity of the heart. It can occur even without blockage of a blood vessel as in inherited electrical disorders of the heart or even as a sequel of an old heart attack with a scar in the heart muscle.
Best treatment for a heart attack of course in the early hours is of course removal of the block by angioplasty (primary angioplasty). Next best option if this is not logistically feasible is dissolving the clot using medicines (thrombolytic therapy).
Primary angioplasty done without initially attempting thrombolytic therapy. If thrombolytic therapy fails and then angioplasty is done, it is called rescue angioplasty. When angioplasty is done for a person have chest pain on exertion, as a planned procedure, without a recent heart attack, it is called elective angioplasty. When a person having recurrent chest pain, but not yet having a full fledged heart attack undergoes angiography and then immediate angioplasty if a critical block is detected, it is known as adhoc angioplasty. Angiography is the visualization of blood vessels, usually by injecting iodinated medications into them and taking cine X-ray images using specialized equipment in a specialized suite known as cardiac catheterization laboratory. When the procedure is done to visualize the blood vessels of the heart, it is known as coronary angiography.
