BACKGROUND: Antihypertension medication (antihypertensive) adherence lowers risk of cardiovascular disease (CVD); few studies have examined this association among older adults. METHODS AND RESULTS: We assessed this association among Medicare fee-for-service beneficiaries aged 66 to 79 years who were newly diagnosed with hypertension and initiated on antihypertensives in 2008-2009 (n=155 597). We calculated proportion of days covered (PDC) during follow-up, using proportional subdistribution hazard models, to examine association between antihypertensive adherence and a composite CVD outcomes, including first incident of fatal/nonfatal acute myocardial infarction, ischemic heart disease, stroke/transient ischemic attack, and heart failure...

A case of a 32-year-old nulliparous white woman referred for a 5-year history of severe hypertension, hypokalemia, and resultant systolic dysfunction is presented. She additionally had a left ventricular ejection fraction of 30% including left ventricular dilation and normal left ventricular mass index, as measured by cardiac magnetic resonance imaging when she initially presented to us. Her history revealed that her severe hypertension episodes were monthly and would occur around the catamenial (menses-associated) time...

Ischemia-reperfusion (IR)-induced acute lung injury (ALI) is implicated in several clinical conditions including lung transplantation, cardiopulmonary bypass surgery, re-expansion of collapsed lung from pneumothorax or pleural effusion and etc. IR-induced ALI remains a challenge in the current treatment. Carbonic anhydrase has important physiological function and influences on transport of CO2. Some investigators suggest that CO2 influences lung injury. Therefore, carbonic anhydrase should have the role in ALI...

In patients with inflammatory bowel disease (IBD) there is an increased incidence of thromboembolic events. We report a case of a female, age 14, with a 6 months history of diarrhea with occasional presence of red blood and with a very distended abdomen with evident ascites. The diagnosis was Budd-Chiari syndrome (BCS) in ulcerative colitis (UC). Therapy with subcutaneous low molecular weight heparin, methylprednisolone, mesalazine was started. Clinical and radiological features quickly improved. No thrombophilia abnormality nor other risk factor for thrombosis were detected...

INTRODUCTION AND HYPOTHESIS: There is limited data available regarding the risk for perioperative cardiac morbidity following pelvic reconstructive surgery (PRS). We sought to determine the incidence of cardiac arrest and myocardial infarction within 30 days of pelvic organ prolapse (POP) surgery and determine which factors may contribute to an increased risk of these complications. METHODS: Using the American College of Surgeons National Quality Improvement Program (NSQIP) database, we identified patients who underwent PRS procedures between 2010 to 2015 using Current Procedural Terminology (CPT) codes...

In response to myocardial infarction (MI), time-dependent leukocyte infiltration is critical to program the acute inflammatory response. Post-MI leukocyte density, residence time in the infarcted area, and exit from the infarcted injury predict resolving or nonresolving inflammation. Overactive or unresolved inflammation is the primary determinant in heart failure pathology post-MI. Here, our review describes supporting evidence that the acute inflammatory response also guides the generation of healing and regenerative mediators after cardiac damage...

Coarctation of the aorta is an uncommon cause of treatment-resistant hypertension in adults. It is typically detected and treated in infancy or childhood with surgical or endovascular procedures. Most cases of recurrence of coarctation after repair occur in childhood or early adulthood; recurrence in older persons (>70 years) has rarely been reported. A 73-year-old woman was referred to us for the management of treatment-resistant hypertension accompanied by symptoms of claudication and headaches, which had resulted in multiple emergency room visits...

Exogenous intravenous (IV) adenosine and epoprostenol are effective vasodilator agents, causing a substantial reduction in pulmonary vascular resistance in patients affected by idiopathic pulmonary arteriolar hypertension (PAH). Their action, in patients with PAH associated with other pathological conditions, is not well defined. In the present paper the authors retrospectively analyzed the acute hemodynamic effects of intravenous adenosine and epoprostenol in 30 consecutive patients (mean age: 58 ± 15 years; 21 females, and 9 males) affected by PAH associated with other pathological conditions, as determined by changes from baseline in systemic and pulmonary hemodynamic parameters...

Stroke is a leading cause of adult disability worldwide. Improving stroke outcome requires an orchestrated interplay that involves up regulation of pro-survival pathways and a concomitant suppression of pro-apoptotic mediators. In this investigation, we assessed the involvement of eNOS in the AT1 blocker-mediated protective and pro-recovery effects in animals with hypertension. We also evaluated the effect of acute eNOS inhibition in hypertensive animals. To achieve these goals, spontaneously hypertensive rats (SHR) were implanted with blood pressure transmitters, and randomized to receive either an eNOS inhibitor (L-NIO) or saline one hour before cerebral ischemia induction...

Tumor necrosis factor alpha (TNFα) is a pro-inflammatory cytokine implicated in cardiovascular and autonomic regulation via actions in the central nervous system. TNFα(-/-) mice do not develop angiotensin II (ANG II)-induced hypertension, and administration of TNFα into the bloodstream of rats increases blood pressure and sympathetic tone. Recent studies have shown that lesion of the subfornical organ (SFO) attenuates the hypertensive and autonomic effects of TNFα, while direct administration of TNFα into the SFO increases blood pressure, suggesting the SFO to be a key site for the actions of TNFα...

REVIEW
Jennifer J DuPont, Iris Z Jaffe
Since the mineralocorticoid receptor (MR) was cloned 30 years ago, it has become clear that MR is expressed in extra-renal tissues, including the cardiovascular system, where it is expressed in all cells of the vasculature. Understanding the role of MR in the vasculature has been of particular interest as clinical trials show that MR antagonism improves cardiovascular outcomes out of proportion to changes in blood pressure. The last 30 years of research have demonstrated that MR is a functional hormone-activated transcription factor in vascular smooth muscle cells and endothelial cells...

Within the cohort of patients suffering from idiopathic pulmonary arterial hypertension (IPAH) is a group that responds dramatically (VR-PAH) to an acute vasodilator challenge and that has excellent long-term hemodynamic improvement and prognosis on high dose calcium channel blockers compared with vasodilator non-responders (VN-PAH). For the purposes of diagnosing VR-PAH, there is to date no test to replace the acute vasodilator challenge. However, recent studies have identified markers that may aid in the identification of VR-PAH, including peripheral blood lymphocyte RNA expression levels of desmogelin-2 and Ras homolog gene family member Q, and plasma levels of provirus integration site for Moloney murine leukemia virus...

We aimed to investigate the efficacy of four severity-of-disease scoring systems in predicting the 28-day survival rate among patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD) requiring emergency care. Clinical data of patients with AECOPD who required emergency care were recorded over 2 years. APACHE II, SAPS II, SOFA, and MEDS scores were calculated from severity-of-disease indicators recorded at admission and compared between patients who died within 28 days of admission (death group; 46 patients) and those who did not (survival group; 336 patients)...
