#1
REVIEW
John G McCarron, Matthew D Lee, Calum Wilson
The endothelium is the single layer of cells that lines the entire cardiovascular system and regulates vascular tone and blood-tissue exchange, recruits blood cells, modulates blood clotting, and determines the formation of new blood vessels. To control each function, the endothelium uses a remarkable sensory capability to continuously monitor vanishingly small changes in the concentrations of many simultaneously arriving extracellular activators that each provides cues to the physiological state. Here we suggest that the extraordinary sensory capabilities of the endothelium do not come from single cells but from the combined activity of a large number of endothelial cells...

Craig K Ewart, Gavin J Elder, Randall S Jorgensen, Sheila T Fitzgerald
OBJECTIVES: A social action theory of chronic stress proposes that agonistic striving (seeking to influence or control others) impairs cardiovascular health by magnifying the impact of high adversity-induced cortisol levels on blood pressure. We tested three predictions of social action theory: (1) the social action theory taxonomy of regulatory strivings characterizes young adults from high-adversity neighborhoods; (2) high cortisol levels predict high blood pressure more reliably in the subgroup with the agonistic striving profile than in subgroups with other profiles; (3) the association of higher cortisol and higher blood pressure with agonistic striving is not explained by negative affect (depressive symptoms/dysphoria, anger, hostility)...

Two cases of patients that developed right ventricular failure (RVF) after cardiac valve surgery are presented with a narrative revision of the literature. RVF involves a great challenge due to the severity of this condition; it has a low incidence among non-congenital cardiac surgery patients, is more likely associated with cardiovascular and pulmonary complications related to cardiopulmonary bypass (CPB), and is a cause of acute graft failure and of a higher early mortality in cardiac transplant. The morphologic and hemodynamic characteristics of the right ventricle and some specific factors that breed pulmonary hypertension after cardiac surgery are in favor of the onset of RVF...

REVIEW
Rashmi Ramachandran, Vimi Rewari
Neuroendocrine tumors which have the potential to secrete catecholamines are either associated with sympathetic adrenal (pheochromocytoma) or nonadrenal (paraganglioma) tissue. Surgical removal of these tumors is always indicated to cure and prevent cardiovascular and other organ system complications associated with catecholamine excess. Some of these tumors have malignant potential as well. The diagnosis, localization and anatomical delineation of these tumors involve measurement of catecholamines and their metabolic end products in plasma and urine, (123)I-metaiodobenzylguanidine scintigraphy, computed tomography, and/or magnetic resonance imaging...

BACKGROUND: A recent study reported that morning hypertension is associated with poor cardiovascular outcomes in hypertensive patients. However, it is unclear whether morning hypertension associated with sustained nocturnal hypertension and that associated with morning blood pressure (BP) surge differ in terms of their effects on cardiovascular target organ damage and clinical outcomes. The present study aimed to determine the association of morning hypertension with/without nocturnal hypertension with vascular target organ damage and central hemodynamics in patients at high risk for cardiovascular disease...

BACKGROUND: The evolution of T1ρ and of other endogenous contrast methods (T2, T1) in the first month after reperfused myocardial infarction (MI) is uncertain. We conducted a study of reperfused MI in pigs to serially monitor T1ρ, T2 and T1 relaxation, scar size and transmurality at 1 and 4 weeks post-MI. METHODS: Ten Yorkshire swine underwent 90 min of occlusion of the circumflex artery and reperfusion. T1ρ, T2 and native T1 maps and late gadolinium enhanced (LGE) cardiovascular magnetic resonance (CMR) data were collected at 1 week (n = 10) and 4 weeks (n = 5)...

Cardioprotective efficacy of remote ischemic preconditioning (RIPC) remains controversial. Experimental studies investigating RIPC have largely monitored cardiovascular changes during index ischemia and reperfusion with little work investigating changes during RIPC application. This work aims to identify cardiovascular changes associated with autonomic nervous system (ANS) activity during RIPC and prior to index ischemia. RIPC was induced in anesthetized male C57/Bl6 mice by four cycles of 5 min of hindlimb ischemia using inflated cuff (200 mmHg) followed by 5 min reperfusion...

A 63-year-old male was diagnosed as having chronic phase CML in 2001. He obtained a major molecular response with imatinib (IM). In 2012, amulodipin was started for hypertension. In January 2013, IM was switched to nilotinib (NIL) in a clinical trial, and in February 2015, NIL was discontinued because MR(4.5) had been maintained for two years. One month later, he was admitted to our hospital because of headache and high blood pressure (194/108 mmHg). His urine test showed protein 3+ and occult blood 2+. His eGFR rapidly deteriorated from 45...

OBJECTIVE: Endovascular aneurysm repair (EVAR) of abdominal aortic aneurysms (AAAs) has gained widespread use through a solid reputation of safety and effectiveness. However, some issues, such as endoleaks and sac growth over time, still arise as important concerns. Antiplatelet therapy, mandatory as secondary prevention of cardiovascular disease, may play a role in both phenomena by interfering with blood clotting properties and the inflammatory process associated with AAA. We analyzed whether different antiplatelet therapies were independent risk factors for type II endoleak (T2E) persistence and midterm sac growth after EVAR...

BACKGROUND AND OBJECTIVE: Cardiovascular (CV) risk stratification is a highly complex process involving an extensive set of clinical trials to support the clinical decision-making process. There are many clinical conditions (e.g. diabetes, obesity, stress, etc.) that can lead to the early diagnosis or establishment of cardiovascular disease. In order to determine all these clinical conditions, a complete set of clinical patient analyses is typically performed, including a physical examination, blood analysis, electrocardiogram, blood pressure (BP) analysis, etc...
