A pilot randomized controlled trial that evaluated the effect of remote ischemic preconditioning (RIPC) on clinical outcomes following major vascular surgery was performed. Eligible patients were those scheduled to undergo open abdominal aortic aneurysm repair, endovascular aortic aneurysm repair, carotid endarterectomy, and lower limb revascularization procedures. Patients were randomized to RIPC or to control groups. The primary outcome was a composite clinical end point comprising any of cardiovascular death, myocardial infarction, new-onset arrhythmia, cardiac arrest, congestive cardiac failure, cerebrovascular accident, renal failure requiring renal replacement therapy, mesenteric ischemia, and urgent cardiac revascularization. Secondary outcomes were components of the primary outcome and myocardial injury as assessed by serum troponin values. The primary outcome occurred in 19 (19.2%) of 99 controls and 14 (14.1%) of 99 RIPC group patients (P = .446). There were no significant differences in secondary outcomes. Our trial generated data that will guide future trials. Further trials are urgently needed.

A higher incidence of cardiovascular disease (CVD) has been observed in several chronic inflammatory diseases. However, data on sarcoidosis are limited.In this study, 345 patients with incident sarcoidosis in Olmsted County (Minnesota, USA) during 1976-2013 were identified based on comprehensive medical record review. 345 sex- and age-matched comparators were also identified from the same underlying population. Medical records were individually reviewed for CVD, including coronary artery disease, congestive heart failure, atrial fibrillation, cerebrovascular accident, transient ischaemic attack, peripheral arterial disease and abdominal aortic aneurysm. Cox proportional hazards models with adjustment for age, sex, calendar year and cardiovascular risk factors were used to compare the rate of development of CVD between cases and comparators.The prevalence of CVD before the index date was not significantly different between the two groups. Adjusting for age, sex and calendar year, the risk of incident CVD after the index date was significantly elevated among patients with sarcoidosis with an adjusted hazard ratio of 1.57 (95% CI 1.15-2.16). Adjustment for cardiovascular risk factors yielded an adjusted hazard ratio of 1.65 (95% CI 1.08-2.53). Significantly increased risk was also observed for several types of CVD, including coronary artery disease, congestive heart failure, atrial fibrillation and cerebrovascular accident.Increased incidence of CVD among patients with sarcoidosis was demonstrated in this population-based cohort, even after controlling for baseline traditional atherosclerotic risk factors.

Aortocaval fistula (ACF) occurs in <1% of all abdominal aortic aneurysms (AAAs), and in 3% to 7% of all ruptured AAAs. The triad of clinical findings of AAA with ACF are abdominal pain, abdominal machinery bruit, and a pulsating abdominal mass. Other findings include pelvic venous hypertension (hematuria, oliguria, scrotal edema), lower-limb edema with or without arterial insufficiency or venous thrombus, shock, congestive heart failure, and cardiac arrest. Surgery is the main treatment modality. We report successful surgical treatment in a patient with a ruptured AAA with ACF who presented with cardiogenic shock.

Rupture with fistulization of an abdominal aortic aneurysm with the vena cava is a rare complication and typically presents with congestive cardiac failure. Embolization of a thrombus from the aneurysm into the vena cava can however present in the absence of failure symptoms which can make it difficult to diagnose clinically without cross sectional imaging.
