Telmisartan, an angiotensin receptor blocker (ARB), is indicated for the treatment of essential hypertension. This study aimed to develop a mechanistic model of telmisartan drug effect in human using non-invasive markers. Data were acquired from a previous study where telmisartan 80 mg was given once daily for 6 days. Systolic (SBP) and diastolic blood pressure (DBP) and heart rate (HR) were measured before dosing for day 1 to 5 and serially after the last dose. Mean arterial pressure (MAP) and pulse pressure (PP) were calculated from SBP and DBP...

The use of intra-aortic balloon counter-pulsation for circulatory support in pregnant women with cardiac failure is limited to several case reports. Few publications have addressed the use of intra-aortic balloon counter-pulsation during delivery. We report a case using prophylactic intra-aortic counter-pulsation during the management of a cesarean delivery in a patient with peripartum cardiomyopathy. A 28-year-old primigravid female at 37weeks of gestation was admitted with signs of worsening heart failure, and transthoracic echocardiography revealed a decreased left ventricular ejection fraction of 25%...

BACKGROUND: Lipoprotein(a) [Lp(a)] is an inherited atherogenic lipoprotein and an independent risk factor for atherosclerotic cardiovascular disease; however, its clinical role remains limited. OBJECTIVE: We hypothesized that Lp(a) screening in high cardiovascular risk patients could provide insight into disease pathogenesis and modify physician behavior for treatment intensification targeting traditional risk factors when Lp(a)-related risk was identified. METHODS: We screened 113 patients presenting electively for percutaneous coronary intervention (PCI) for Lp(a) who met any of the following criteria: (1) premature coronary artery disease (male age <55 years, female age <65 years); (2) family history of premature coronary artery disease; (3) progression to PCI despite well-controlled traditional risk factors (blood pressure <140/90 mm Hg, and low-density lipoprotein cholesterol <100 mg/dL, and HbA1c <7%, and nonsmoker); or (4) progression to PCI despite at least moderate intensity statin use (simvastatin 40, atorvastatin 40-80, or rosuvastatin 20-40 mg daily)...

The effects of retinoids on adrenal aldosterone synthase gene (CYP11B2) expression and aldosterone secretion are still unknown. We therefore examined the effects of nuclear retinoid X receptor (RXR) pan-agonist PA024 on CYP11B2 expression, aldosterone secretion and blood pressure, to elucidate its potential as a novel anti-hypertensive drug. We demonstrated that PA024 significantly suppressed angiotensin II (Ang II)-induced CYP11B2 mRNA expression, promoter activity and aldosterone secretion in human adrenocortical H295R cells...

BACKGROUND: Few data exist on malignant middle cerebral artery infarction (MMI) among patients with acute ischemic stroke (AIS) after endovascular treatment (ET). Numerous predictors of MMI evolution have been proposed, but a comprehensive research of patients undergoing ET has never been performed. Our purpose was to find a practical model to determine robust predictors of MMI in patients undergoing ET. METHODS: Patients from a prospective single-center database with AIS secondary to large intracranial vessel occlusion of the anterior circulation, treated with ET, were retrospectively analyzed...

OBJECTIVE: Smooth muscle (SM) 22α, an actin-binding protein, displays an upregulated expression as a marker during cellular senescence. However, the causal relationship between SM22α and senescence is poorly understood. This study aimed to investigate the role of SM22α in angiotensin II (Ang II)-induced senescence of vascular smooth muscle cells (VSMCs). APPROACH AND RESULTS: We prepared a model of VSMC senescence induced by Ang II and found that the expression of SM22α in VSMCs was increased in response to chronic Ang II treatment...

We evaluated the contribution of tumor necrosis factor-α receptor 1 (TNFR1) to ethanol-induced hypertension and vascular oxidative stress and the possible role of perivascular adipose tissue (PVAT) in such responses. Male C57BL/6 wild-type (WT) or TNFR1-deficient mice (TNFR1(-/-)) were treated with ethanol (20% vol/vol) for 12 weeks. Ethanol induced an increase in blood pressure in WT mice and TNFR1(-/-) at 4 and 5 weeks of treatment, respectively. Treatment with ethanol increased tumor necrosis factor-α and interleukin-6 levels in aortas with or without PVAT (PVAT+ and PVAT-, respectively) from WT mice, but not TNFR1(-/-)...

REVIEW
Belinda Setters, Holly M Holmes
Hypertension is common among adults and is associated with significant morbidity and mortality and should be routinely addressed in primary care practice. Optimal blood pressure targets have evolved in the past decade with the release of large studies including older persons. However, controversy remains regarding the treatment of older and frail patients. The relationship between blood pressure treatment and falls or cognitive impairment is still an area of concern and debate. A strategy to address hypertension in older persons should consider an individual's fitness and the likelihood of adverse effects and worsening of conditions that adversely affect quality of life...
