Ruff, MD, MPH, senior investigator of TIMI Group and director GeneralCardiology, Cardiovascular Division, Brigham and Women's Hospital. Patient Demographics: Patients on APT had a higher rate of coronary artery disease (70% vs. 42%), previous heartattacks (36% vs. 16%), and peripheral artery disease (15% vs. 11%).
High degree of awareness of heartattack symptoms in the community will go a long way in seeking early treatment. For life threatening diseases like heartattack, early recognition of symptoms and prompt reporting to the emergency department is highly desirable.
In general, risk factors for stroke and some forms of heart disease are similar. Strokes due to blocks in blood vessels, can be seen along with blocks in blood vessels of the heart. Stroke can occur after a heartattack as well. Heartattack damages a part of the heart muscle.
Pain of a heartattack occurs in a similar location as effort angina but is more severe. Chest pain may be associated with undue sweating, anxiety and sometimes undue awareness of heart beats known as palpitation. Chest pain of heartattack is not relieved by rest unlike effort angina.
A view from the right side of the heart shows the right coronary artery which has been marked as RCA. This is another major blood vessel supplying oxygenated blood to the heart. Sudden blockage of any of these blood vessels can cause a heartattack. CT angiogram is useful in detecting major blocks in these blood vessels.
They are more prone to have heartattack and stroke (brain attack), due to disease of their blood vessels. Partial obstruction to one blood vessel is an important reason for lower blood pressure in that arm. Obstruction of blood vessel in the arm is a pointer to disease of blood vessels elsewhere in the body.
Pericarditis can occur after a heartattack due to damage following a loss of blood supply. Viral infection is an important cause of pericarditis and pericardial effusion. Bacterial infections in the adjacent organs like lungs can also rarely spread to the pericardium, causing pericarditis.
When the heart is not able to pump enough blood for the needs of the body and the blood pressure falls, it is known as cardiogenic shock. Most important cause of cardiogenic shock is a heartattack. If cardiogenic shock is due to a heartattack, immediate angiography, and removal of the block by angioplasty are useful.
First degree AV block can sometimes be a manifestation of diseases like rheumatic fever, a disease which affects predominantly the joints and the valves of the heart. First degree heart block can also occur in a heartattack involving the lower part of the heart known as inferior wall myocardial infarction.
Hence blockage of LAD can cause a major heartattack, which can sometimes be fatal. LAD is short for left anterior descending coronary artery. LAD is usually the largest branch of the left main coronary artery which supplies the major portion of the left ventricle. That is why LAD has been called a widow maker artery.
