Myocardial infarction unstable angina associated

Obstacles remained as PTCA was not universally available and often associated with considerable time delay, especially in off peak hours. In the National Registry of Myocardial Infarction-2 (NRMI-2 >27,000 patients), total ischemia time (symptom onset to balloon inflation) was 3.9 h with onset to hospital arrival 1.6 h [45]. Unadjusted in-hospital mortality was higher in patients treated later. Door to balloon time > 2 h was related to in-hospital death (41-62% adjusted odds increase) and centers who treat >3 STEMIs/month had improved in-hospital mortality compared to less experienced facilities (Figs. 5.4 and 5.5). Lastly, similar to trials of unstable angina, PTCA was plagued by high restenosis rates... 

There has been some concern about the safety of the calcium channel blockers. In particular, reports indicated that certain calcium channel blockers, such as the short-acting form of nifedipine, may be associated with an increased risk of myocardial infarction in certain patients (older patients with hypertension, patients with unstable angina).21,29... 

The main argument in favor of a beneficial effect of ACE inhibition on coronary heart diseases comes from the pooled results of the SOLVE) treatment trial, the SOLVE) prevention trial, and the SAVE, AIRE, and TRACE studies, which indicate a 21% (95% Cl, 11-29%, p <. 001) relative risk reduction for myocardial infarction associated with ACE inhibitor therapy. Enalapril (SOLVE)) significantly reduced hospitalization for unstable angina, and captopril (SAVE) reduced revascularization procedures (291). In patients treated for 38 to 42 months with enalapril or captopril and selected on the basis of a reduction in ejection fraction with or without heart failure, it is necessary to treat 49 patients to avoid one myocardial infarction (95% Cl 32-117). 

A retrospective chart review was conducted to explore metamfetamine-associated acute coronary syndromes in patients who presented to the emergency room at a University Center between 1994 and 1996 (1). There were 36 admissions, three of which were repeat patients. Nine of these patients had acute coronary syndrome. Of these, one had an acute anterior Q wave myocardial infarction with cardiac arrest, seven had non-Q wave myocardial infarctions, and one had unstable angina. There were potentially life-threatening cardiac complications in three subjects (8%). The authors suggested that acute coronary syndromes and life-threatening complications associated with the use of metamfetamine are not uncommon, as evidenced by their experience in this study. 

Total loss of coronary blood flow results in a clinical syndrome associated with what is known as ST segment elevation AMI (STE AMI). Partial loss of coronary perfusion if severe also can lead to necrosis as well—which is generally less severe and is loiown as NSTEMI (non-ST-elevation myocardial infarction), and other events of still lesser severity may be missed entirely or called angina, which can range from stable to unstable. 

A phenol peel should of course not be performed after myocardial infarction or cardiac decompensation. Unstable angina also rules out a phenol peel, as the stress associated with a peel could trigger an angina attack. No clear link has ever been established between a personal medical history of a heart condition, if currently stabilized, and the incidence of cardiovascular complications during a phenol peel. Apart from arrhythmias, to the best of my knowledge there is no mention in the literature of any serious heart problems occurring as a complication of a phenol peel. ... 

Chronic stable angina, unstable angina, and myocardial infarction are all forms of coronary disease (also known as coronary artery disease or ischemic heart disease). These are the most common forms of hypertension-associated target-organ disease. /3-Blocker therapy... 

A middle-aged man, after an episode of retrosternal chest pressure with radiation to the neck and associated nausea and diaphoresis while at rest, was given a diagnosis of unstable angina and possibly myocardial infarction. Subsequent laboratory findings of increased serum levels of troponin I and eardiac enzymes were consistent with the diagnosis. 

Acute coronary syndromes (ACS) encompass a wide spectrum of coronary artery disease from unstable angina (UA) to myocardial infarction (MI). According to the 2007 report from the American Heart Associations and Stroke Statistics Committee, about 700,000 Americans are expected to suffer from their first MI yearly, with almost 500,000 recurrent Mis occurring annually (1). Coronary heart disease (CHD) is responsible for about one out of every five deaths in the United States ACS is the cause of over 1.5 million hospitalizations yearly and therefore plays a significant role in the cost of our health care.

The three major forms of angina are (a) angina of effort, which is associated with a fixed plaque that partially occludes one or more coronaries (b) vasospastic angina, which involves unpredictably timed, reversible coronary spasm and (c) unstable angina, which often immediately precedes a myocardial infarction and requires emergency treatment.
