Thrombolysis and Q Wave Versus Non-Q Wave First Acute Myocardial Infarction: A GUSTO-I Substudy

Abstract

Patients with no ECG confounding factors or evidence of previous infarction who do not develop Q waves after thrombolysis have a better 30-day and 1-year prognosis than patients with a Q wave infarction.

Long-Term Mortality Rates Reflect Progressive Prognostic Benefits of Thrombolysis in Patients with First Acute Myocardial Infarction

“…Extensive data are available on the long-term prognosis of patients who experienced a first acute myocardial infarction (AMI) [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12]. The most commonly chosen parameters for conducting these evaluations are age, gender, concomitant disease, AMI type, localization and severity, drug therapy as well as the role played by thrombolysis.…”

“…The most commonly chosen parameters for conducting these evaluations are age, gender, concomitant disease, AMI type, localization and severity, drug therapy as well as the role played by thrombolysis. Controlled clinical studies on the efficacy of thrombolysis in AMI patients have been given major attention [7, 11, 12, 13, 14, 15, 16, 17]. For the most part, these studies were conducted on selective samples according to strict exclusion and eligibility criteria.…”

Usefulness of Q waves on ECG for the prediction of contractile reserve after acute myocardial infarction

“…The presence of pathological 'Q' waves, on electrocardiograph (ECG), post acute myocardial infarction (AMI) have been widely considered to reflect irreversibly scarred myocardium and thus nonviability [1]. However, it has been demonstrated that 'Q' waves can be dynamic rather than permanent [2] and despite their presence there is evidence of preserved myocardial viability following AMI [3].…”

“…Sixteen deaths were reported on the first day, and the total number was revised up to 67 by the second day. Based on newspaper reports accessed online, we attempted to determine a possible etiology [1][2][3].…”

Sudden deaths following the unexpected demise of a popular politician in India

“…Impact of home-based, supervised exercise on congestive heart failure In 2003, the American Heart Association published a statement on exercise in congestive heart failure (CHF) patients that declared exercise to be safe and beneficial for that patient population, specifically regarding exercise capacity and quality of life [1]. Shortterm exercise training in selected CHF patients has positive effects on many different outcomes, including physical performance [2,3], quality of life [2,4], and overall morbidity and mortality [2,5].…”
