Patent foramen ovale closure versus medical therapy after cryptogenic stroke: An updated meta-analysis of all randomized clinical trials

Background: Cryptogenic strokes can be attributed to paradoxical emboli through patent foramen ovale (PFO). However, the effectiveness of PFO closure in preventing recurrent stroke is uncertain and the results of previous randomized clinical trials (RCTs) have been inconclusive. Hence, this study pro- vides an updated meta-analysis of all RCTs comparing PFO closure with medical therapy for secondary prevention of cryptogenic stroke. Methods: All RCTs were identified by a comprehensive literature search of PubMed, Embase, the Cochrane Collaboration Central Register of Controlled Trials, Scopus, and Clinicaltrials.gov. The primary outcome was recurrent ischemic stroke and secondary outcomes were transient ischemic at- tack (TIA), all-cause mortality, new-onset atrial fibrillation (AF), serious adverse events, and major bleeding. Results: Five RCTs with 3440 participants were included in the present study (1829 patients under- went PFO closure and 1611 were treated medically). Pooled analysis showed a statistically significant reduction in the rate of recurrent stroke with PFO closure in comparison to medical therapy (OR 0.41; 95% CI 0.19–0.90; p = 0.03). However, there were no statistically significant reductions of recurrent TIAs (OR 0.77; 95% CI 0.51–1.14; p = 0.19) or all-cause mortality (OR 0.76; 95% CI 0.35–1.65; p = 0.48). The risk of developing new-onset AF was increased significantly with PFO closure (OR 4.74; 95% CI 2.33–9.61; p < 0.0001), but no significant differences in terms of serious adverse events or major bleeding between both groups. Conclusions: Patent foramen ovale closure in adults with recent cryptogenic stroke was associated with a lower rate of recurrent strokes in comparison with medical therapy alone.

Invasive Hemodynamic Monitoring in Cardiogenic Shock Is Associated With Lower In-Hospital Mortality

Background: There is increasing utilization of cardiogenic shock treatment algorithms. The cornerstone of these algorithms is the use of invasive hemodynamic monitoring (IHM). We sought to compare the in-hospital outcomes in patients who received IHM versus no IHM in a real-world contemporary database. Methods and Results Patients with cardiogenic shock admitted during October 1, 2015 to December 31, 2018, were identified from the National Inpatient Sample. Among this group, we compared the outcomes among patients who received IHM versus no IHM. The primary end point was in-hospital mortality. Secondary end points included vascular complications, major bleeding, need for renal replacement therapy, length of stay, cost of hospitalization, and rate of utilization of left ventricular assist devices and heart transplantation. Propensity score matching was used for covariate adjustment. A total of 394 635 (IHM=62 565; no IHM=332 070) patients were included. After propensity score matching, 2 well-matched groups were compared (IHM=62 220; no IHM=62 220). The IHM group had lower in-hospital mortality (24.1% versus 30.6%, P\u3c0.01), higher percentages of left ventricular assist devices (4.4% versus 1.3%, P\u3c0.01) and heart transplantation (1.3% versus 0.7%, P\u3c0.01) utilization, longer length of hospitalization and higher costs. There was no difference between the 2 groups in terms of vascular complications, major bleeding, and the need for renal replacement therapy. Conclusions: Among patients with cardiogenic shock, the use of IHM is associated with a reduction in in-hospital mortality and increased utilization of advanced heart failure therapies. Due to the observational nature of the current study, the results should be considered hypothesis-generating, and future prospective studies confirming these findings are needed

Bilateral pulmonary nodules and intravascular pulmonary histiocytosis: A rare presentation of hemophagocytic lymphohistiocytosis secondary to Epstein-Barr Virus infection

A 61-year-old male presented with worsening dyspnoea and constitutional symptoms for few weeks followed by bloody diarrhoea and loss and fever. Physical exam revealed tachycardia, respiratory distress, and splenomegaly without lymphadenopathy. Work up showed pancytopenia, hypofibrinogenemia, acute kidney injury requiring haemodialysis, high ferritin level, positive IgG and IgM for EBV and positive soluble CD25. Chest CT scan showed bilateral pulmonary nodules. Lung biopsy showed intravascular pulmonary histiocytosis while bone marrow biopsy was negative for hemophagocytes. A diagnosis of hemophagocytic lymphohistiocytosis (HLH) was made based on fulfilling the diagnostic criteria and systemic steroids were initiated, which improved the patient's condition gradually with resolution of dyspnoea, AKI and pancytopenia. Repeat chest CT scan showed resolution of bilateral pulmonary nodules. The patient was transferred to a tertiary centre to receive HLH-specific therapy. We present a rare presentation of HLH with steroid-responsive bilateral pulmonary nodules and a rare histopathologic finding of pulmonary intravascular histiocytosis, which has never been described in HLH or the lung tree

Vitamin D deficiency and risk of cardiovascular diseases: a narrative review

Abstract Vitamin D, a fat-soluble prohormone, has wide-ranging roles in the regulation of many physiological processes through their interactions with the vitamin D receptors (VDR). It plays a major role in bones and calcium metabolism. Vitamin D deficiency is not uncommon and it has been associated with many health-related issues, including skeletal and non-skeletal complications. The association of low vitamin D and cardiovascular diseases and risk factors has been explored in both animal and human studies. However, studies and trials on the effect of vitamin D supplementation on cardiovascular risk factors and hypertension are conflicting with inconsistent results. Therefore, large, well-powered randomized controlled trials are warranted. If successful, supplementation with easy and low-cost vitamin D can impact our health positively. Here, we summarized the evidence for the association of vitamin D, cardiovascular diseases and risk factors, including coronary artery diseases, stroke, and hypertension, and mortality, with special consideration to resistant hypertension

Alcohol septal ablation vs myectomy for symptomatic hypertrophic obstructive cardiomyopathy: Systematic review and meta‐analysis

Background Surgical myectomy (SM) and Alcohol septal ablation (ASA) are effective therapies for patients with hypertrophic cardiomyopathy who remain symptomatic despite medical therapy. A plethora of data has recently emerged on the long‐term outcomes of these procedures. We hence sought to perform an updated meta‐analysis comparing both procedures. Methods Studies reporting long‐term (\u3e3‐years) outcomes of SM and/or ASA were included. The primary endpoint was all‐cause mortality. Secondary endpoints included cardiovascular mortality, sudden cardiac death (SCD), reintervention, and complications including death, pacemaker implantation, and stroke. Results Twenty‐two ASA cohorts (n = 4213; follow‐up = 6.6‐years) and 23 SM cohorts (n = 4240; follow‐up = 6.8‐years) were included. Septal myectomy was associated with higher periprocedural mortality and stroke (2% vs 1.2%, P = 0.009 and 1.5% vs 0.8% P = 0.013, respectively), but ASA was associated with more need of pacemaker (10% vs 5%, P \u3c 0.001). During long‐term follow‐up, all‐cause mortality, cardiovascular mortality, and sudden cardiac death rates were 1.5%, 0.4%, and 0.3% per person‐year in the ASA group and 1.1%, 0.5%, and 0.3% per person‐year in the SM group (P = 0.21, P = 0.53, P = 0.43), respectively. Repeat septal reduction intervention(s) were more common after ASA (11% vs 1.5%, P \u3c 0.001). Conclusion Compared with SM, ASA is associated with lower periprocedural mortality and stroke but higher rates of pacemaker implantations and reintervention. However, there was no difference between ASA and SM with regards to long‐term all‐cause mortality, cardiovascular mortality, or SCD

The dawn of aspirin free strategy after short term dual antiplatelet for percutaneous coronary intervention: meta-analysis of randomized controlled trials

There is still a debate about the safety and efficacy of an aspirin free strategy after percutaneous coronary intervention (PCI). Hence, we performed a meta-analysis comparing aspirin free strategy to dual antiplatlets therapy (DAPT). Randomized trials (RCTs) comparing aspirin free strategy to DAPT in patients who received PCI were included. The primary outcome of interest was bleeding, defined per the Bleeding Academic Research Consortium (BARC). Secondary outcomes included major adverse cardiovascular and cerebrovascular events (MACE); defined as all-cause mortality, myocardial infarction or stroke, the individual component of MACE and stent thrombosis. A total of 4 RCTs with 29,089 patients were included. There was significant reduction in BARC 2,3 or 5 bleeding events in patients who were treated with aspirin free strategy versus DAPT (HR 0.61, 95% CI 0.39-, p = 0.03, I2 = 89%). Moreover, although there was a trend of reduced major bleeding (BARC 3 or 5) outcomes in the aspirin free strategy group compared to the DAPT group, this did not achieve statistical significance (HR 0.63, 95% CI 0.37-1.06, p = 0.08, I2 = 795). Additionally, there was no difference between the aspirin free strategy and DAPT in term of MACE (HR 0.92, 95% CI 0.82-1.03, p = 0.13, I2 = 0%), all-cause mortality (HR 0.89, 95% CI 0.77-1.04, p = 0.15, I2 = 0%), MI (HR 0.89, 95% CI 0.74-1.08, p = 0.24, I2 = 0%), stroke (HR 1.13, 95% CI 0.65-1.99, p = 0.66, I2 = 60%) or stent thrombosis (HR 0.1.01, 95% CI 0.83-1.22, p = 0.93, I2 = 0%). Aspirin free strategy is as effective as DAPT in reducing MACE with better safety profile in term of bleeding

Fifteen-Year Trends in Incidence of Cardiogenic Shock Hospitalization and In-Hospital Mortality in the United States.

BACKGROUND: There is a lack of contemporary data on cardiogenic shock (CS) in-hospital mortality trends. METHODS AND RESULTS: Patients with CS admitted January 1, 2004 to December 31, 2018, were identified from the US National Inpatient Sample. We reported the crude and adjusted trends of in-hospital mortality among the overall population and selected subgroups. Among a total of 563 949 644 hospitalizations during the period from January 1, 2004, to December 30, 2018, 1 254 358 (0.2%) were attributed to CS. There has been a steady increase in hospitalizations attributed to CS from 122 per 100 000 hospitalizations in 2004 to 408 per 100 000 hospitalizations in 2018 (Ptrendtrendtrendtrend CONCLUSIONS: Hospitalizations attributed to CS have tripled in the period from January 2004 to December 2018. However, there has been a slow decline in CS in-hospital mortality during the studied period. Further studies are necessary to determine if the recent adoption of treatment algorithms in treating patients with CS will further impact in-hospital mortality

The state of renal sympathetic denervation for the management of patients with hypertension: A systematic review and meta-analysis.

BackgroundSympathetic nervous system plays a central role in the development and persistence of essential hypertension. In recent years renal sympathetic denervation (RSD) has emerged as a promising option for the treatment of patients with hypertension.MethodsWe conducted a literature search of PubMed, EMBASE, Cochrane library and Clinicaltrials.gov from inception through April 20, 2020. Outcomes of interest were change in 24-hour ambulatory systolic (ASBP) or diastolic blood pressure (ADBP) and change in office systolic (OSBP) or diastolic blood pressure (ODBP). We pooled data from randomized controlled trials (RCTS) comparing RSD to sham procedures in the management of hypertension using the random effect model.ResultsA total of 1,363 patients from eight studies were included in the current meta-analysis. The mean age of the included patients was 56 ± 2.6 years, 29% were women and the median duration of maximum follow up was 6-month (range 3-12 month). There was more reduction favoring RSD in ASBP (Weighted mean difference [WMD] -3.55; 95% CI -4.91 - -2.19, p < .001, I2 = 0%), ADBP (WMD -1.87; 95% CI -3.07 - -0.66, p = .002, I2 = 43%), OSBP (WMD -5.5; 95% CI -7.59 - -3.40, p < .001, I2 = 7%) and ODBP (WMD -3.20; 95% CI -4.47 - -1.94, p < .001, I2 = 14%).ConclusionThe use of RSD for the management of hypertension resulted in effective reduction in the ambulatory and office blood pressure compared to sham procedure. Adequately powered RCTs of RSD are needed to confirm safety, reproducibility and assess the impact on clinical outcomes
