Tpa Heart Attack
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
Drugs, genes: Cocaine or methamphetamine come to mind when you see a 19 year old with a heart attack, although an autoimmune disease, hypertrophic cardiomyopathy, or severe hyperlipidemia might have a myocardial infarct at that age as well... Drugs are the cause more commonly seen in our society, however. ...Read more
Call 911!!!: If you feel pressure-type chest pain, going to your shoulder or jaw, and have associated shortness of breath, these are classic signs. Remember, only about 1/3 of heart attacks present with these classic signs. Some show up as nausea, vague discomfort, or no signs at all. If you have any question, err on the side of caution and get to the er immediately. Chew an adult Aspirin while waiting. ...Read more
Supply & demand: In simple terms, it is a mismatch between the supply of oxygen and nutrients to heart muscle and the needs/demands of the heart muscle. In effect, heart muscle suffocates. This can be caused by narrowed or blocked vessels (coronary arteries) limiting blood flow. Stress tests on treadmill increases work of heart and determine if you can increase supply to match demand. ...Read more
Heart attack: Increasing chest pain/pressure at rest or with decreasing exercise trigger is a frequent sign. Along with the chest symptom could be cold, clammy, lightheaded feeling, perhaps jaw or arm pain, nausea too. If you have any question of it being an impending heart attack should get to the hospital asap. ...Read more
It's simple: Economics. Remember supply and demand? Well, when the blood supply to an area of the heart does not meet demand of the cells to survive, tissue begins to die and that is a "heart attack". The most likely cause is obstruction of a blood vessel supplying the heart in the form of a clot or plaque. ...Read more
Heart attack: Sudden chest pain-often described as discomfort (tightness or pressure like) in upper chest associated with radiation to jaw or arm, with sweating/shortness of breath/lightheadedness. Any or all of these features can indicate a heart attack. This classic presentation, however, is only described in a third of cases. Atypical chest pain/ or no symproms occur in 2/3 patients. ...Read more
Angina pectoris =substernal pressure, pain with radiation to the neck or left or right arm and shoulder.
Some will have abdominal pain-and be confused with gallbladder or stomach symptoms.
Ladies seem to have less classic// or tolerate pain better than men.
Relief with Nitroglycerin is very suggestive.
A feeling of impending doom, pallor, sweating suggest a bad day! ...Read more
It is a confusing question
it is possible to have more heart attacks if you have had one. It is possible to have cardiac arrest if you have had a heart attack if that is your question. ...Read more
There are only: Limited data available to answer your question. Some studies indicate about a 53% incidence of atherosclerotic involvement of the Left main or Left anterior descending arteries. If the patient is symptomatic and treated, the MI would be avoided. If not then a widow maker MI might occur. The former occurs much more frequently than the latter so I would say by my experience it is not common. ...Read more
No: Heartburn does not cause heart attacks. However, both can cause chest pain. If you have new or worsening chest pain, go to the er immediately. It may just be heartburn but you don't know for sure until heart attack is ruled out. Heartburn is easily treatable, not permanent or life-threatening, and reversible. Heart attacks are none of those. ...Read more
" heart burn" is most commonly acid reflux when stomach acid squirts back up into your esophagus and even mouth giving a burning sensation.
A heart attack gives a similar pain but the reflux does not affect your heart but is does effect your esophagus whichis not designed to have acid in the mucosa. If you are having heartburn get checked to make sure it is heartburn an not heart related. ...Read more
Varied: The arm symptom of heart attack could be described as heaviness, soreness or pain or even numbness. It is usually correlated with the chest symptoms and other symptoms such as sob, diaphoresis, nausea, vomiting, dizziness and has to be correlated with risk factors. If in doubt, at least an ekg can help with suspicion and for the doctor to make a decision on treatment. ...Read more
ST Elevation: Changes on an ekg can be highly suggestive of a heart attack (especially major ones called st elevation mi's (a segment on the ekg called the st segment is noted to be higher than the baseline) but that does not mean a normal ekg can exclude a less severe heart attack. ...Read more
Q waves: Some heart attacks do not show and even ones that do, may only be temporary. That said, q waves, if of sufficient voltage and if they follow known patterns, are the way of diagnosing heart attack by ekg. (caution: not all Q waves are indicative of heart attack!). ...Read more
