Heart Attack
"A heart attack occurs when the supply of blood and oxygen to an area of heart muscle is blocked, usually by a clot in a coronary artery. ...Prompt treatment of a heart attack can help prevent or limit lasting damage to the heart and can prevent sudden death. ...The sooner treatment begins, the better your chances of recovering."
Highlighted Article[Complications of an unrecognized myocardial infarction] (Ned Tijdschr Geneeskd. 2005)
"Around one-third of patients who have a myocardial infarction do not have chest pain but experience shortness of breath, autonomic nervous symptoms (sweating, nausea, vomiting), extreme and inexplicable tiredness and fainting. These atypical symptoms should suggest myocardial infarction. In order to avoid high morbidity and death from complications such as arrhythmias, heart failure, rupture and aneurysm formation it is important that a patient who has had a myocardial infarction should be treated as soon as possible ..."

Myocardial Infarction (Heart Attack)
General Information
NEWS:
Getting Swifter Treatment for Deadliest Heart Attacks "In technical terms, the attack is called an ST-elevation myocardial infarction (STEMI), referring to a feature seen on an electrocardiogram. In real life, it is total blockage of a heart artery, which can be fatal unless treated quickly in one of two ways. Those options: Drug therapy to clear away a clot blocking the artery, or angioplasty, the insertion of a balloon to push the artery open. And those treatments must be done quickly -- ideally, within 30 minutes for clot-dissolving drug treatment, and within 90 minutes for angioplasty. But, fewer than half of all STEMI patients get the right treatment at the right time …"
Heart Attack Boosts Diabetes Risk "After a heart attack, the risk of developing diabetes and so-called pre-diabetes rises steeply, a new study finds. In fact, recent heart attack patients are up to four-and-a-half times more likely to develop diabetes compared with the general population and more than 15 times more likely to develop high blood sugar, according to the report in the Aug. 25 issue of The Lancet."
Heart attack deaths plummet in just 6 years "The promising trend parallels the growing use of cholesterol-lowering drugs, powerful blood thinners, and angioplasty, the procedure that opens clogged arteries, the researchers said. … And the heart attack patients treated most recently were far less likely to have another attack within six months of being hospitalized when compared to the patients treated six years earlier — a sign that the more aggressive efforts of doctors in the last few years are working."

JOURNAL ARTICLES:
Acute myocardial infarction and underlying stenosis severity. (Catheter Cardiovasc Interv. 2007) "CONCLUSION:: In contrast to what is often believed, the majority of myocardial infarctions occurs in significant stenosis."
Cardiopulmonary resuscitation by bystanders with chest compression only (SOS-KANTO): an observational study (The Lancet 2007) "Cardiac-only resuscitation by bystanders is the preferable approach to resuscitation for adult patients with witnessed out-of-hospital cardiac arrest, especially those with apnoea, shockable rhythm, or short periods of untreated arrest."
Depression and anxiety as predictors of heart rate variability after myocardial infarction. (Psychol Med. 2007 )
Depression is a risk factor for mortality after myocardial infarction: fact or artifact? (J Am Coll Cardiol. 2007)
Does Comorbidity Account for the Excess Mortality in Patients With Major Bleeding in Acute Myocardial Infarction? (Circulation. 2007)
Effect of first myocardial ischemic event on renal function. (Am J Cardiol. 2007) "In conclusion, a first ischemic cardiac event appears to enhance the natural decrease in renal function. Because even mild renal dysfunction should be considered a major cardiovascular risk factor after myocardial infarction, increased renal function loss after an ischemic cardiac event could add to the risk for subsequent cardiovascular morbidity, thus closing a vicious circle."

Oxidative stress and total antioxidant status in myocardial infarction. (Singapore Med J. 2007) "RESULTS: The levels of total cholesterol, low density lipoprotein cholesterol, triglycerides, MDA and nitrite/nitrate were found to be significantly high, while high density lipoprotein cholesterol and total antioxidant capacity were significantly low in MI patients compared to controls."
Pathophysiology of acute myocardial infarction. (Med Clin North Am. 2007) "More than 80% of acute myocardial infarcts are the result of coronary atherosclerosis with superimposed luminal thrombus. Uncommon causes of myocardial infarction include coronary spasm, coronary embolism, and thrombosis in nonatherosclerotic normal vessels."

Predictors of stroke in high-risk patients after acute myocardial infarction: insights from the VALIANT trial (EHJ 2007) "Conclusion Among high-risk patients presenting with MI but without initial neurological symptoms, the risk of stroke 6 weeks thereafter is 0.94% (95% CI 0.78–1.09). Of the most powerful baseline predictors of stroke, DBP and AF are amenable to therapeutic interventions and thus merit special attention in these patients."
Prognostic value of blood pressure measured during hospitalization after acute myocardial infarction: an insight from survival trials. (J Hypertens. 2007) "CONCLUSION: In post-MI patients with left ventricular ejection fraction less than 40% or asymptomatic ventricular arrhythmia, reduced blood pressure measured during hospitalization after MI significantly predicts all-cause mortality and arrhythmic mortality, and can be reliably used to identify patients who are at risk of dying after MI."
Relation of C-reactive protein and new-onset atrial fibrillation in patients with acute myocardial infarction. (Am J Cardiol. 2007) "In conclusion, in a large cohort of patients with AMI, there was a graded positive association between increased CRP and new-onset AF. Inflammation may contribute to the development of AF in the setting of AMI."
Short- and long-term mortality after acute myocardial infarction: comparison of patients with and without diabetes mellitus. (Eur J Epidemiol. 2007) "Our findings in an unselected cohort covering a complete nation show a significantly higher long-term mortality after a first acute myocardial infarction in diabetic patients. Yet, short-term mortality is not significantly higher in diabetic patients. Risks appear to be equally elevated in men and women."
