• Pls,include the advantages and disavantages of each technique. you should focus on the complexity and varied nature of CVDs or how the different stages in the development of CVDs can be investigation.

• Answer:

  TO BEGIN THE MOST BASIC TEST IS AN EKG, IT DETECTS IRREGULAR HEART BEATS AND PATTERNS, WHICH CAN DETERMINE IF A HEART ATTACK HAS OCCURED. IT IS QUICK AND FAIRLY IN-EXPENSIVE. SOME OTHER MORE COMPLEX TESTS WOULD INCLUDE A STRESS TEST, WHICH UTILIZE NUCLEAR MED. COMPONENTS, OR TREADMILL, OR MEDS GIVEN TO SPEED UP THE HEART. IT CAN BE ORDERED IF AN EKG IS ABNORMAL. IT TAKES MORE TIME AND IS MORE EXPENSIVE. THERE IS ALSO AN ULTRA-SOUND TEST CALLED AN AORTIC DUPLEX WHICH IS NOT SO COMPLICATED, IT CAN CHECK FOR PROBLEMS IN THE AORTA. IF A SEVERE ENOUGH PROBLEM IS DETECTED SUCH A BLOCKAGE, THE DOCTOR MIGHT ORDER A HEART CATH. A SMALL OPENING IS CUT INTO THE FEMORAL ARTERY AND A WIRE WITH A SMALL LENS IS ATTATCHED AND FED THROUGH TO THE HEART, WHILE THE DOCTOR WATCHES ON A SPECIAL SCREEN, IT IS USED TO DETECT THE SEVERITY OF BLOCKAGES. THIS REQUIRES A HOSPITAL STAY OF ABOUT 12 HOURS. PRESSURE IS APPLIED AFTER THE TEST IS OVER, AND YOU STAY IN A HOSPITAL ROOM WITH WEIGHT APPLIED OVER THE GROIN AREA, SO THAT BLEEDING DOES NOT OCCUR. IT IS A FAIRLY EXPENSIVE PROCEDURE.
