Subjects
*HEART failure, *MORTALITY, *TREATMENT effectiveness, *GLOMERULAR filtration rate, CARDIOVASCULAR disease related mortality
Abstract

Introduction: Previous trials showed that tolvaptan improves acute heart failure (HF). However, the optimal timing for administering tolvaptan to achieve the best outcome remains unclear. Therefore, the current study investigated the relationship between the timing of tolvaptan treatment initiation and clinical outcomes in patients with acute decompensated HF. Methods: We prospectively evaluated 201 patients with acute decompensated HF, randomly divided into 2 groups based on the timing of tolvaptan initiation. The early group was administered tolvaptan approximately 1 week after day 1 or 2 (n = 104), whereas the late group was administered the same drug 1 week after the early group (n = 97). Results: All-cause mortality, cardiovascular death, and hospitalization during the follow-up period were comparable between both groups. The early group had shorter durations of oxygenation, carperitide infusion, and hospitalization than the late group (p = 0.013, 0.003, 0.006, respectively). The early group demonstrated a significantly faster decrease in pleural effusion than the late group (p = 0.001). The 2 groups had comparable maximum and minimum serum sodium and potassium levels and minimum estimated glomerular filtration rates during hospitalization. The early group spent significantly less money on all diuretics administered over the first 2 weeks and on tolvaptan and carperitide administered during the hospitalization period than the late group (p < 0.001). Conclusions: Early and short-term administration of tolvaptan was feasible, contributed to a more rapid improvement in patients with acute decompensated HF, and reduced health-care costs.

Subjects
ACUTE coronary syndrome, OPTICAL coherence tomography, PERCUTANEOUS coronary intervention
Abstract

Introduction: Areas covered: In this review, we outline the underlying causes of acute coronary syndrome (ACS) as evaluated by optical coherence tomography (OCT). We report both the definitions of each mechanism and its frequency as reported in the literature to date. Finally, we present an algorithm based on the findings in the review that gives an outlined approach to perform intervention on ACS patients. Expert opinion: Although the most common and most accepted intervention in ACS cases is stent implantation, data suggest a stentless approach in cases of plaque erosion, which generally occurs in younger patients presenting with an acute coronary syndrome that have TIMI flow of 2/3 and either a small or large burden of thrombus and underlying stenosis of less than 50%.

26. Staged Percutaneous Coronary Intervention with Rotational Atherectomy or Bypass Surgery in Chronic Hemodialysis and Severely Calcified Left Main True Bifurcation Lesion: A Case Report and Literature Review.

Abstract

Previous observational studies and meta-analyses reported that the optimal strategy of coronary revascularization (percutaneous coronary intervention [PCI] and bypass surgery) for anatomically complex coronary artery lesions in the chronic hemodialysis setting is still controversial because the long-term outcomes were superior with coronary artery bypass grafting, especially with regard to repeat revascularization; however, short-term mortality with PCI was significantly lower because it is less invasive. Moreover, no guidelines show a strategy for this setting. We report the case of a patient with chronic dialysis and calcified left main true bifurcation lesion who underwent staged PCI with rotational atherectomy and minimally invasive direct coronary artery bypass for in-stent restenosis who died of non-occlusive mesenteric ischemia.

27. Paclitaxel-related balloons and stents for the treatment of peripheral artery disease: Insights from the Food and Drug Administration 2019 Circulatory System Devices Panel Meeting on late mortality.

Author

Abstract

Following the December 2018 publication of a meta-analysis by Katsanos et al reporting higher rates of long-term mortality with the utilization of paclitaxel-related devices (balloons and stents) when compared to control in femoropopliteal arteries, the US Food and Drug Administration (FDA) issued a safety alert in January 2019 and further detailed the implications for future clinical use of these devices in March 2019. The FDA convened a public meeting of the Circulatory System Devices Panel of the Medical Devices Advisory Committee in June 2019. This report summarizes the proceedings of this meeting and the panel's response to the 12 questions posed by the FDA related to the potentially increased late mortality of drug-coated balloons and drug-eluting stents with paclitaxel in patients with peripheral arterial disease.

34. Clinical outcomes of complete revascularization using either angiography-guided or fractional flow reserve-guided drug-eluting stent implantation in non-culprit vessels in ST elevation myocardial infarction patients: insights from a study based on a systematic review and meta-analysis.

Abstract

Current guidelines recommend that percutaneous coronary intervention (PCI) should be restricted to the culprit vessel in ST elevation myocardial infarction (STEMI) patients with multi-vessel disease (MVD) and without cardiogenic shock. However, newer data suggests that performing complete revascularization (CR) in MVD patients may lead to better outcomes compared to intervention in the culprit vessel only. The aim of this meta-analysis is to examine the available data to determine if CR (using either angio- or fractional flow reserve guidance-FFR) following primary PCI in STEMI patients without cardiogenic shock impacts clinical outcomes. Meta-analysis was performed by conducting a literature search of PubMed from January 2004 to July 2017. Pooled estimates of outcomes, presented as odds ratios (OR) [95% confidence intervals], were generated using random-effect models. A total of 9 studies (3317 patients) were included. CR showed a significant MACE reduction (OR 0.49, 95% CI 0.36-0.66, p < 0.001); All-cause mortality (OR 0.69, 95% CI 0.48-0.98, p = 0.04) and repeat revascularization (OR 0.38, 95% CI 0.28-0.51, p < 0.001) at ≥ 12 months follow-up. The FFR-guiding CR group presented a MACE reduction (odds ratio 0.52, 95% CI 0.30-0.90, p = 0.02) due to a decrease of repeat revascularization (OR 0.41, 95% CI 0.21-0.80, p = 0.009). Overall, performing complete revascularization in STEMI patients showed a MACE reduction, all-cause death and repeat revascularization. Compared to culprit-only revascularization, treating multi-vessel disease in STEMI patients using FFR guidance is associated with decreased incidence of MACE, due to a decreased rate of revascularization.
