Randomized Controlled Trial Multicenter Study Clinical TrialSuppression of paroxysmal atrial tachyarrhythmias--results of the SOPAT trial.
The indication to treat paroxysmal atrial fibrillation (PAF) is controversial. The Suppression of Paroxysmal Atrial Tachyarrhythmias (SOPAT) trial was designed to answer the following questions: (1) What is the average rate of spontaneous events of symptomatic PAF with and without anti-arrhythmic medication? (2) what is the prevalence of severe side-effects? and (3) is the fixed combination of Quinidine + Verapamil inferior to the efficacy of sotalol or not? ⋯ Taken together, anti-arrhythmic therapy with the fixed combination of Quinidine + Verapamil is as effective as Sotalol in the reduction of the recurrence rate of symptomatic PAF with a low but definite risk of severe side-effects.

Multicenter Study Comparative StudyAssociation between the low activity genotype of catechol-O-methyltransferase and myocardial infarction in a hypertensive population.
Estrogens regulate several biological processes involved in the pathogenesis of myocardial infarction. Catechol-O-methyltransferase (COMT) is a key enzyme in the degradation of estrogens. There is a functional polymorphism in the COMT gene (Val158Met), affecting the activity of the enzyme. We investigated if the low activity genotype of COMT is associated with an altered risk of myocardial infarction. ⋯ Our findings suggest that the low activity COMT genotype is protective against myocardial infarction. One may speculate that the altered estrogen status could be involved in this effect.

Multicenter StudyPredictors of in-hospital mortality in 1333 patients with acute myocardial infarction complicated by cardiogenic shock treated with primary percutaneous coronary intervention (PCI); Results of the primary PCI registry of the Arbeitsgemeinschaft Leitende Kardiologische Krankenhausärzte (ALKK).
Aims Acute myocardial infarction complicated by cardiogenic shock is associated with an exceedingly high mortality, even if patients are treated with early reperfusion therapy. The aim of this study was to evaluate predictors of in-hospital mortality of a large cohort of consecutive patients with cardiogenic shock treated with primary percutaneous coronary intervention (PCI). Methods and results Between July 1994 and March 2001 all interventions performed in 80 centres in Germany were prospectively entered into the primary PCI registry of the ALKK. ⋯ Conclusions In-hospital mortality in patients with acute myocardial infarction complicated by cardiogenic shock remains high, even with early interventional therapy. However, our data demonstrate that the PCI in these high-risk patients is feasible in a wide spectrum of community hospitals with acceptable success rates. Our results seen in connection with the results of the randomized SHOCK study advocate an early invasive approach in younger patients with cardiogenic shock, while the best strategy in elderly patients is still a matter of debate.

Randomized Controlled Trial Multicenter Study Clinical TrialFlu vaccination in acute coronary syndromes and planned percutaneous coronary interventions (FLUVACS) Study.
We have previously reported a significant benefit of vaccination against flu on the incidence of a single and composite end-point of death, myocardial infarction or recurrent ischaemia in patients with myocardial necrosis and planned percutaneous coronary interventions. To determine whether the observed benefits of vaccination against flu were maintained beyond the winter season a 1-year follow-up was conducted. ⋯ Influenza vaccination may reduce the risk of death and ischaemic events in patients suffering from infarction and post-angioplasty during flu season. This effect was significantly evident at 1-year follow-up. Larger confirmatory studies are needed to evaluate the real impact on flu vaccination on outcome after acute coronary syndromes.

Multicenter StudyIntra-aortic balloon counterpulsation in US and non-US centres: results of the Benchmark Registry.
To examine differences in patient characteristics and outcomes in 19636 patients enrolled in the USA and 3027 patients enrolled in other countries undergoing intra-aortic balloon pump (IABP) counterpulsation. ⋯ IABP counterpulsation is deployed at an earlier clinical stage in US patients. Mortality rates are higher for non-US patients, particularly for patients with non-surgery cardiac interventions, even after adjusting for risk factors. Complication rates were low. Physicians should therefore not be reluctant to use IABP in high-risk patients undergoing cardiac procedures.
