Six days of oral V administration centered on the C day, combined with P, significantly reduce the incidence of early recurrences of AF compared with P alone.

The flecainide infusion test has been proposed to screen candidates for hybrid pharmacological and ablation therapy. We report the long-term follow-up of 154 consecutive patients with paroxysmal or persistent atrial fibrillation (AF) who developed atrial flutter (AFL) during flecainide infusion (IC AFL), treated with inferior vena cava-tricuspid annulus isthmus catheter ablation and oral flecainide (hybrid therapy). Over a mean of 54.1 +/- 13.1 months 82 patients (53%) remained free of AF and AFL. Flecainide was discontinued because of adverse effects in 6 patients (4%). A history of persistent AF, and the documentation of >/=1 spontaneous AFL episode before the flecainide test were independent predictors of successful hybrid therapy. In patients with paroxysmal AF without documented spontaneous AFL, the long-term efficacy of hybrid therapy was 38.5% (P = 0.03). The flecainide infusion test reliably detects candidates for hybrid therapy. The efficacy of this therapy is maintained over the long-term with a high patient compliance.

One of the potential cardiotoxic action of anti-inflammatory drugs is the occurrence of heart failure (HF), due to their effects on fluid retention and blood pressure. The risk of hospitalization for HF is roughly doubled for both Coxibs, cyclooxygenase-1 (COX-1) and cyclooxygenase-2 (COX-2) inhibitors, and all the conventional nonsteroidal anti-inflammatory drugs (NSAIDs). These drugs are also associated with a risk of vascular thrombosis, which for NSAIDs is different in relation to their different ability to inhibit COX-1 and COX-2.The cardiovascular toxicity of these drugs in the direction of HF follow different pathways respect to their related vascular thrombosis toxicity and involves, in particular, the renal prostaglandins, PGE 2 and prostacyclin, mostly synthesized by COX-2.In the kidneys the PGs perform a direct vasodilatory action, e.g. by means of non-contrasting angiotensin mechanisms, and for this reason nimesulide effects on renal microcirculation are independent from the prevalence of intrarenal renin angiotensin aldosterone system (RAAS) activity. Conversely, nimesulide reduces sodium tubular urinary flow only in presence of intrarenal RAAS.

Background Recently, the COMPASS trial demonstrated that dual therapy reduced cardiovascular outcomes compared with aspirin alone in patients with stable atherosclerotic disease. Methods and Results We sought to assess the proportion of patients eligible for the COMPASS trial and to compare the epidemiology and outcome of these patients with those without COMPASS inclusion or with any exclusion criteria in a contemporary, nationwide cohort of patients with stable coronary artery disease (CAD). Among the 4068 patients with detailed information allowing evaluation of eligibility, 1416 (34.8%) did not fulfill the inclusion criteria (COMPASS-Not-Included), 841 (20.7%) had exclusion criteria (COMPASS-Excluded) and the remaining 1811 (44.5%) were classified as COMPASS-Like. At 1 year, the incidence of major adverse cardiovascular event (MACE), a composite of cardiovascular death, myocardial infarction and stroke, was 0.9% in the COMPASS-Not-Included and 2.0% in the COMPASS-Like (p = 0.01), and 5.0% in the COMPASS-Excluded group (p < 0.0001 for all comparisons). Among the COMPASS-Like population, patients with multiple COMPASS enrichment criteria presented a significant increase in the risk of MACE (from 1.0% to 3.3% in those with 1 and ≥3 criteria, respectively; p = 0.012), and a modest absolute increase in major bleeding risk (from 0.2% to 0.4%, respectively; p = 0.46). Conclusions In a contemporary real-world cohort registry of stable CAD, most patients resulted as eligible for the COMPASS. These patients presented a considerable annual risk of MACE that consistently increases in the presence of multiple risk factors.
