How Does A Heart Attack Affect Blood Pressure
Myocardial Infarction means some of the heart muscle dies because of insufficient oxygen supply. Most often this occurs because the coronary artery is blocked by plaque & clot. Other causes include tears in the artery wall, extremely high oxygen demand (eg, rapid arrhythmia, heart valve disorder, or severe systemic illness.) Prompt treatment can minimize heart damage & ...Read more
Requires both muscle: to work harder to drive blood forward & ?es valve leaflet loads to block reverse blood flow. Heart muscle requires more blood flow for more work (more susceptible to damage of artery Ds), muscle gets thicker/stronger but also stiffer (no longer allows blood return from veins at low pressure) over time. Both lead to ?ed heart attack rates, enlargement, congestive failure, atrial fibrillation, etc. ...Read more
Depends: This is very individual. If you have had high blood pressure for a long time, your body is used to it and may tolerate it longer. If you for example take Cocaine or other drugs that raise your blood pressure suddenly, even a small increase can give you a heart attack. No guarantees either way.. ...Read moreSee 1 more doctor answer
Different: Severe acute hypertension can cause tear of aorta and sudden death or need for emergency surgery. Can happen anytime with elevated bp but scary at 180 systolic and 120 diastolic. Can also cause left ventricular strain and hypertrophy and heart failure but usually not a heart attack acutely. ...Read more
Recently blood pressure gets high sometime. Does it take years for high blood pressure to cause heart attack?
High CHOL : Specially high LDL and low hdl, may accumulate through a complex process of injury at the endothelium. Inner part of the coronary artery. That accumulation it's call the atheromatous plague. Also compose of other inflammatory cells. That formation may grow and occlude the artery increasing risk of heart attack. ...Read more
Artery hardening.: The arterial walls start to thicken and harden in response to elevated blood pressures. This is part of the process that leads to atherosclerosis or hardening of the arteries. High blood pressure is considered one of the primary risk factors for coronary heart disease. Blood pressure is the force. Years of high blood pressure can damage your arteries, causing them to harden and narrow. ...Read moreSee 1 more doctor answer

Does atenalol help prevent stroke and heart attacks? When does someone need to be on blood pressure medicine?
140/90: Atenolol reduces the risk of second heart attack in those who have had one. For primary prevention, it reduces the risk of stroke and heart attack in people with elevated blood pressure. If your BP is averaging >140/90, you should be on some form of treatment. Atenolol is one of many good treatments. ...Read more
Blood pressure is a measurement of the force placed on the blood vessels and is comprised of the "systolic" pressure (the top number on a blood pressure meter) which is the peak pressure when the heart is pumping, and the "diastolic" pressure (the bottom number on a blood pressure meter) which is the pressure during the resting phase ...Read more
