Endovascular Treatment of Resistant and Uncontrolled Hypertension Therapies on the Horizon
The treatment of resistant hypertension has undergone remarkable advancements in recent years. Endovascular radio frequency renal sympathetic denervation (RSD) has shown initial success in treating resistant hypertension by targeting the connection between the brain and renal sympathetic nerves. However, the encouraging results of first-generation RSD have been tempered by important procedural limitations and a need for long-term results of safety and efficacy. In an effort to build on early clinical success, several second-generation RSD technologies are now being developed that may improve procedural safety and efficacy. Preliminary evidence for some of the latest technologies is now available. In this review, we summarize the current evidence in support of RSD and consider unique features of several new technologies that are likely to refine the endovascular treatment of resistant hypertension
Sex Differences in Trends and In-Hospital Outcomes among Patients with Critical Limb Ischemia: A Nationwide Analysis
Background
Critical limb ischemia (CLI) represents the most severe form of peripheral artery disease and is associated with significant mortality and morbidity. Contemporary data comparing the sex differences in trends, revascularization strategies, and in-hospital outcomes among patients with CLI are scarce.
Methods and Results
Using the National Inpatient Sample database years 2002 to 2015, we identified hospitalizations for CLI. Temporal trends for hospitalizations for CLI were evaluated. The differences in demographics, revascularization, and inâhospital outcomes between both sexes were compared. Among 2 400 778 CLI hospitalizations, 43.6% were women. Women were older and had a higher prevalence of obesity, hypertension, heart failure, and prior stroke. Women were also less likely to receive any revascularization (34.7% versus 35.4%, P\u3c 0.001), but the trends of revascularization have been increasing among both sexes. Revascularization was associated with lower inâhospital mortality among women (adjusted odds ratio [OR], 0.76; 95% CI, 0.71â0.81) and men (adjusted OR, 0.69; 95% CI, 0.65â0.73). On multivariable analysis adjusting for patientâ and hospitalârelated characteristics as well as revascularization, women had a higher incidence of inâhospital mortality, postoperative hemorrhage, need for blood transfusion, postoperative infection, ischemic stroke, and discharge to facilities compared with men.
Conclusions
In this nationwide contemporary analysis of CLI hospitalizations, women were older and less likely to undergo revascularization. Women had a higher incidence of inâhospital mortality and bleeding complications compared with men. Sexâspecific studies and interventions are needed to minimize these gaps among this highârisk population
Comparative Outcomes of Interventions for Femoropopliteal Chronic Total Occlusion Versus Non-Chronic Total Occlusion Lesions From the Multicenter XLPAD Registry
Background Endovascular intervention of femoropopliteal chronic total occlusions (CTOs) is technically more complex. However, there is lack of comparative analysis between CTO and non-CTO femoropopliteal interventions. Methods and Results We report procedural details and outcomes of patients treated for femoropopliteal CTO and non-CTO lesions in the XLPAD (Excellence in Peripheral Artery Disease) registry (NCT01904851) between 2006 and 2019. Primary outcomes were procedural success and 1-year major adverse limb events, a composite of all-cause death, target limb revascularization, or major amputation. Analysis included 2895 patients (CTO: n=1516 patients; non-CTO: n=1379 patients) with 3658 lesions (CTO: n=1998 lesions; non-CTO: n=1660 lesions). Conventional balloon angioplasty (20.86% versus 33.48%
Door-to-balloon Time for ST-elevation MI in the Coronavirus Disease 2019 Era
In patients presenting with ST-elevation MI, prompt primary coronary intervention is the preferred treatment modality. Several studies have described improved outcomes in patients with door-to-balloon (D2B) and symptom onset-to-balloon (OTB) times of less than 2 hours, but the specific implications of the coronavirus disease 2019 (COVID-19) pandemic on D2B and OTB times are not well-known. This review aims to evaluate the impact of COVID-19 on D2B time and elucidate both the factors that delay D2B time and strategies to improve D2B time in the contemporary era. The search was directed to identify articles discussing the significance of D2B times before and during COVID-19, from the initialization of the database to December 1, 2020. The majority of studies found that onset-of-symptom to hospital arrival time increased in the COVID-19 era, whereas D2B time and mortality were unchanged in some studies and increased in others
