Heart Attack Symptoms, Causes and TestsArticle by admin
A Heart Attack occurs if the flow of oxygen-rich blood to a section of heart muscle suddenly becomes blocked. If blood flows isn’t restored quickly, the section of heart muscle begins to die.SYMPTOMS of the heart attacks are uncomfortable pressure on chest, pain spreading to the shoulders, neck or arms. The pain may be mild to intense.it may fell like pressure, tightness, burning, or heavy weight. It may be located in the chest, upper abdomen, neck, jaw, or inside the arms or shoulders. Chest discomfort with light-headedness, fainting, sweating, nausea or shortness of breath. Anxiety, nervousness and/or cold, sweaty skin. Paleness or pallor. Increased or irregular heart rate. Feeling of impending doom.CAUSES of heart attacks are Cigarette smoking, Stress or Pain, due to certain drugs such as cocaine, exposure to an environment which is extreme cold. Major risk factors are Smoking, High blood Cholesterol, High blood pressure, Diabetes, Obesity and Overweight.The heart attack tests are ECG, BLOOD TESTS, CORONARY ANGIOGRAPHY, ECHOCARDIOGRAM, CHEST X-RAY, and NUCLEAR SCAN.Electrocardiogram (ECG) , this is a graphic record of the electrical activity of the heart as it contracts and relaxes. The ECG can detect abnormal heartbeats, some areas of damage, inadequate blood flow, and heart enlargement.BLOOD test will be done routinely to check for enzymes or other substances that are released when cells begin to die. These are markers of the amount of damage to your heart.CORONARY ANGIOGRAPHY test is used to check blockages and narrowed areas inside coronary arteries. A fine tube (catheter) is threaded through an artery of arm or leg up into the heart. A dye that shows up on X-ray is then injected into the blood vessel, and the vessels and heart are filmed as the heart pumps. The picture is called an Angiogram.CHEST X-RAY, an X-ray image of your chest allows your doctor to check the size and shape of your heart and its blood vessels.ECHOCARDIOGRAM, this test uses sound waves to produce an image of your heart. During an echocardiogram, sound waves are directed at your heart from a transducer, a wand-like device, held on your chest. An echocardiogram can help identify whether an area of your heart has been damaged by a heart attack and isn’t pumping normally or at peak capacity.NUCLEAR SCAN, this test helps identify blood flow problems to your heart. Small amounts of radioactive material are injected into your bloodstream. Special cameras can detect the radioactive material as it flows through your heart and lungs. Areas of reduced blood flow to the heart muscle -through which less of the radioactive material flows- appear as dark spots on the scan.TREATMENT of Heart attack includes, Anti-platelet medications to prevent formation of blood clots in the arteries, Anti-coagulant medications to prevent growth of blood clots in the arteries, Coronary angiography with either percutaneous trans luminal coronary angioplasty (PTCA) with or without stenting to open blocked coronary arteries,patients whose lungs are very seriously copd prognosis. clot-dissolving medications to open blocked arteries, supplemental oxygen to increase the supply of oxygen to the heart’s muscle, medications to decrease the need for oxygen by the heart’s muscle, medications to prevent abnormal heart rhythms.
