Pathophysiologic Mechanisms

A clear pathogenetic association exists between obesity and arterial hypertension, becoming even more evident in subjects with severe obesity. Bariatric surgery has proved to be the most effective treatment for severe obesity, with its benefits going beyond weight loss. The present review aimed to determine the effects of bariatric surgery on arterial hypertension evident in short- and long-term follow-ups. Moreover, the differences between surgical techniques regarding hypertension remission are described as well as the possible pathophysiologic mechanisms involved. In addition, the effects of bariatric surgery beyond blood pressure normalization are also analyzed, including those on target organs and cardiovascular morbidity and mortality.

Successful lung and heart-lung transplantations were achieved nearly 3 decades ago at a time when medical therapeutic options for patients with pulmonary arterial hypertension were extremely limited. While the medical arsenal for treatment of pulmonary arterial hypertension has expanded considerably since this time, lung and heart-lung transplantations continue to offer potential for improved survival and quality of life for patients who experience disease progression despite medical therapy. The majority of patients with pulmonary hypertension requiring transplantation can be successfully treated with lung transplantation and do not require combined heart-lung transplantation. Advances in surgical techniques, medical management, donor and recipient selection, pharmacologic therapies, and clinical outcomes assessment have led to ongoing improvements in short- and long-term outcomes. Long-term success requires appropriate candidate and donor selection, experienced surgical and medical teams, diligent medical follow-up by the transplant team in collaboration with community medical providers, and excellent patient adherence with post-transplant care and therapy. This article addresses short- and long-term management and complications associated with lung transplantation. Outcomes after transplantation, immunosuppressive management, acute and chronic rejection, medical morbidities, and underlying diagnosis-specific concerns are discussed.

Left Atrial Stiffness

Arterial hypertension (AH) is one of the most significant modifiable risk factors that increase cardiovascular morbidity and mortality worldwide, including Russia. The complex of structural and functional changes in the heart that occurs during AH consists not only in the formation of left ventricular (LV) myocardial hypertrophy, but also in the myocardial stiffness increasing due to collagen formation and cardiomyocytes apoptosis. These abnormalities are substrate for diastolic function disturbances, electrical myocardial instability and ischemia. The article provides a clinical case of amlodipine/lisinopril single-pill combination (A/L SPC) use in real clinical practice in a patient with stage II grade 2 newly diagnosed AH and its effect on blood pressure and echocardiographic myocardial fibrosis markers, including speckle tracking parameters The high antihypertensive efficacy of A/L SPC, a favorable effect on blood pressure circadian rhythm, as well as pronounced target-organ protective properties, in particular the ability to reduce LV and left atrial stiffness, were demonstrated. So, we conclude that A/L SPC improve the elastic properties of the left heart.

The Impact

The aim of this meta-analysis was to review the impact of a Paleolithic diet (PD) on selected health indicators (body composition, lipid profile, blood pressure, and carbohydrate metabolism) in the short and long term of nutrition intervention in healthy and unhealthy adults. A systematic review of randomized controlled trials of 21 full-text original human studies was conducted. Both the PD and a variety of healthy diets (control diets (CDs)) caused reduction in anthropometric parameters, both in the short and long term. For many indicators, such as weight (body mass (BM)), body mass index (BMI), and waist circumference (WC), impact was stronger and especially found in the short term. All diets caused a decrease in total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), and triglycerides (TG), albeit the impact of PD was stronger. Among long-term studies, only PD cased a decline in TC and LDL-C. Impact on blood pressure was observed mainly in the short term. PD caused a decrease in fasting plasma (fP) glucose, fP insulin, and homeostasis model assessment of insulin resistance (HOMA-IR) and glycated hemoglobin (HbA1c) in the short run, contrary to CD. In the long term, only PD caused a decrease in fP glucose and fP insulin. Lower positive impact of PD on performance was observed in the group without exercise. Positive effects of the PD on health and the lack of experiments among professional athletes require longer-term interventions to determine the effect of the Paleo diet on athletic performance.

And Function

The primary goal of this chapter is to provide the reader with an overview of basic renal physiology and function and to review the identification, pathogenesis, and treatment of acute kidney injury following cardiac surgery. Particular focus will be directed toward the diagnostic criteria for acute kidney injury, short- and long-term impacts on patient outcomes, role of novel biomarkers, mechanisms of acute renal injury, general management principles, preventative strategies, and the influence of anesthetic and surgical techniques on its development. The content of this chapter will serve to underscore a particularly harmful but likely underappreciated problem affecting patients in the cardiothoracic critical care setting.

Angiotensin II (ANG II) raises blood pressure partly by stimulating tubular Na+ reabsorption. The effects of ANG II on tubular Na+ transporters (i.e., channels, pumps, cotransporters, and exchangers) vary between short-term and long-term exposure. To better understand the physiological impact, we used a computational model of transport along the rat nephron to predict the effects of short- and long-term ANG II-induced transporter activation on Na+ and K+ reabsorption/secretion, and to compare measured and calculated excretion rates. Three days of ANG II infusion at 200 ng·kg−1·min−1 is nonpressor, yet stimulates transporter accumulation. The increase in abundance of Na+/H+ exchanger 3 (NHE3) or activated Na+-K+-2Cl− cotransporter-2 (NKCC2-P) predicted significant reductions in urinary Na+ excretion, yet there was no observed change in urine Na+. The lack of antinatriuresis, despite Na+ transporter accumulation, was supported by Li+ and creatinine clearance measurements, leading to the conclusion that 3-day nonpressor ANG II increases transporter abundance without proportional activation. Fourteen days of ANG II infusion at 400 ng·kg−1·min−1 raises blood pressure and increases Na+ transporter abundance along the distal nephron; proximal tubule and medullary loop transporters are decreased and urine Na+ and volume output are increased, evidence for pressure natriuresis. Simulations indicate that decreases in NHE3 and NKCC2-P contribute significantly to reducing Na+ reabsorption along the nephron and to pressure natriuresis. Our results also suggest that differential regulation of medullary (decrease) and cortical (increase) NKCC2-P is important to preserve K+ while minimizing Na+ retention during ANG II infusion. Lastly, our model indicates that accumulation of active Na+-Cl− cotransporter counteracts epithelial Na+ channel-induced urinary K+ loss.
