Gender-specific genetic determinants of blood pressure and organ weight: pharmacogenetic approach.

A total genome scan and pharmacogenetic study were designed to search for genetic determinants of blood pressure (BP) as well as heart and kidney weights. Genome scanning was carried out in 266 F(2) intercrosses from Prague hypertensive hypertriglyceridemic rats for phenotypes of organ weights, baseline BP, BP after blockade of the renin-angiotensin system (RAS) by losartan, of the sympathetic nervous system (SNS) by pentolinium, and of the nitric oxide (NO) synthase by N(G)-nitro-L-arginine methyl ester. Pharmacogenetic analysis showed that, in males, BP was controlled by two loci on chromoso

Estimating the societal cost of type 2 diabetes in Malmö, Sweden: a register-based cost analysis.

BACKGROUND: With the prevalence of Type 2 Diabetes (T2D) projected to increase, understanding its potential consequences on healthcare systems is crucial for adequately preparing society to address this growing challenge. In 2019, Malmö, Sweden's third-largest city, joined the Cities for Better Health global initiative to tackle the multifaceted challenges associated with T2D, including its significant economic burden on the healthcare system and the broader community. Understanding the economic burden of T2D on the healthcare system will facilitate optimisation of the initiatives undertaken b

Effects of diabetes and level of glycemia on all-cause and cardiovascular mortality. The San Antonio Heart Study.

OBJECTIVE: Although the level of hyperglycemia is clearly a risk factor for microvascular complications in diabetic patients, its role in macrovascular complications remains controversial. We followed 4,875 subjects (65% Mexican-American) for 7-8 years to investigate the effects of diabetes and hyperglycemia on all-cause and cardiovascular disease (CVD) mortality. These end points were also analyzed according to quartiles of baseline fasting plasma glucose among diabetic participants. RESEARCH DESIGN AND METHODS: The Cox proportional hazards model was used to estimate the relative risks (RRs)

UK Prospective Diabetes Study (UKPDS). VIII. Study design, progress and performance.

The UK Prospective Diabetes Study (UKPDS) is a multi-centre, prospective, randomised, intervention trial of 5100 newly-diagnosed patients with Type 2 (non-insulin-dependent) diabetes mellitus which aims to determine whether improved blood glucose control will prevent complications and reduce the associated morbidity and mortality. Newly presenting Type 2 diabetic patients aged 25-65 years inclusive, median age 53 years, median body mass index 28 kg/m2 and median fasting plasma glucose 11.3 mmol/l, were recruited and treated initially by diet. Ninety five percent remained hyperglycaemic (fastin

Tryptophan and tyrosine catabolic pattern in neuropsychiatric disorders.

Catabolism of tryptophan and tyrosine in relation to the isoprenoid pathway was studied in neurological and psychiatric disorders. The concentration of trytophan, quinolinic acid, kynurenic acid, serotonin and 5-hydroxyindoleacetic acid was found to be higher in the plasma of patients with all these disorders; while that of tyrosine, dopamine, epinephrine and norepinephrine was lower. There was increase in free fatty acids and decrease in albumin (factors modulating tryptophan transport) in the plasma of these patients. Concentration of digoxin, a modulator of amino acid transport, and the act

Increased extracellular volume, reduced stress perfusion, and worse systolic function in Wilson's disease.

BACKGROUND: Wilson's disease (WD) causes intracellular copper accumulation due to a genetic defect in the copper-transporting protein ATP7B. Cardiac involvement has been reported even in young WD patients; however, pathophysiological mechanisms remain unclear. This study aimed to comprehensively assess the myocardium in WD patients without cardiac symptoms using multiparametric cardiovascular magnetic resonance imaging (CMR), including quantitative stress perfusion mapping and strain analysis. METHODS: WD patients and healthy volunteers underwent multiparametric 1.5T CMR, including cine, nati

Whether TM

Percutaneous coronary intervention and 30-day unplanned readmission with chest pain in the United States (Nationwide Readmissions Database).

Percutaneous coronary intervention (PCI) improves anginal chest pain in most, but not all, treated patients. PCI is associated with unplanned readmission for angina and non-specific chest pain within 30-days of index PCI. Patients with an index hospitalization for PCI between January-November in each of the years 2010-2014 were included from the United States Nationwide Readmissions Database. Of 2 723 455 included patients, the 30-day unplanned readmission rate was 7.2% (n = 196 581, 42.3% female). This included 9.8% (n = 19 183) with angina and 11.1% (n = 21 714) with non-specific chest pain.

Bench-to-bedside review: Angiopoietin signalling in critical illness - a future target?

Multiple organ dysfunction syndrome (MODS) occurs in response to major insults such as sepsis, severe haemorrhage, trauma, major surgery and pancreatitis. The mortality rate is high despite intensive supportive care. The pathophysiological mechanism underlying MODS are not entirely clear, although several have been proposed. Overwhelming inflammation, immunoparesis, occult oxygen debt and other mechanisms have been investigated, and - despite many unanswered questions - therapies targeting these mechanisms have been developed. Unfortunately, only a few interventions, usually those targeting mu

Coronary atherosclerosis and chemotherapy: From bench to bedside.

Cardiovascular disease, particularly coronary artery disease, is the leading cause of death in humans worldwide. Coronary heart disease caused by chemotherapy affects the prognosis and survival of patients with tumors. The most effective chemotherapeutic drugs for cancer include proteasome inhibitors, tyrosine kinase inhibitors, immune checkpoint inhibitors, 5-fluorouracil, and anthracyclines. Animal models and clinical trials have consistently shown that chemotherapy is closely associated with coronary events and can cause serious adverse cardiovascular events. Adverse cardiovascular events a

Interventional Cardio-Oncology: Adding a New Dimension to the Cardio-Oncology Field.

The management of cardiovascular disease in patients with active cancer presents a unique challenge in interventional cardiology. Cancer patients often suffer from significant comorbidities such as thrombocytopenia and coagulopathic and/or hypercoagulable states, which complicates invasive evaluation and can specifically be associated with an increased risk for vascular access complications. Furthermore, anticancer therapies cause injury to the vascular endothelium as well as the myocardium. Meanwhile, improvements in diagnosis and treatment of various cancers have contributed to an increase i

Insights into Endothelial Progenitor Cells: Origin, Classification, Potentials, and Prospects.

With the discovery of endothelial progenitor cells (EPCs) in the late 1990s, a paradigm shift in the concept of neoangiogenesis occurred. The identification of circulating EPCs in peripheral blood marked the beginning of a new era with enormous potential in the rapidly transforming regenerative field. Overwhelmed with the revelation, researchers across the globe focused on isolating, defining, and interpreting the role of EPCs in various physiological and pathological conditions. Consequently, controversies emerged regarding the isolation techniques and classification of EPCs. Nevertheless, th

Внезапная сердечная смерть при системном склерозе: диагностика для оценки риска и управления информацией

Сердечное заболевание является одной из основных причин смертности при системном склерозе (SSc), а внезапная сердечно-сосудистая смертность (SCD), как считается, чаще встречается в SSc, чем в целом по населению. Диффузный миокардиальный фиброз, миокардит и ишемическая болезнь сердца широко распространены в SSc и могут быть разумно гипотезы, что будет способствовать повышению риска СКД. Несмотря на это, СКР по-прежнему остается относительно недооцененной зоной SSc, где мало что известно о специфических для SSc факторах риска и возможностях первичной профилактики. В этом обзоре мы представляем о

Micro- and Macrovascular Complications in Early-Onset Type 2 Diabetes in Indians: Prevalence and Predictors in a Prospective Cross-Sectional Study.

Introductionand Aims: The prevalence of T2DM is rising among young people, placing them at greater risk for complications. We studied the prevalence and predictors of micro- and macrovascular complications in early-onset diabetes subjects (EOD, MethodsA total of 800 subjects (400 EOD, 400 LOD), matched for gender and diabetes duration, were prospectively recruited and assessed for the prevalence of peripheral neuropathy, retinopathy, nephropathy, and ASCVD. Multivariate logistic regression analyzed predictors of diabetes complications.ResultsThe median age at diagnosis of diabetes was 35 years

Intractable right coronary artery spasm in the early postoperative period after heart transplantation: a case report.

Coronary artery spasm after heart transplantation is a very rare complication. In one observational study and many anecdotal reports, most cases of coronary artery spasm occurred more than 1 year after surgery and had good outcomes. However, cases of intractable coronary artery spasm during the early postoperative period resulting in fatality are limited. This report presents a case of two cardiac arrests caused by coronary artery spasms within a short period of time after heart transplantation.

Compartment Syndrome of All Extremities in the Setting of COVID-19-Induced Systemic Capillary Leak Syndrome With Superimposed Myositis.

Three years following the pandemic's emergence, COVID-19 has continued to affect much of the symptomatic population with widely varied respiratory complaints, fevers, numerous unexpected prodromal manifestations, and unknown long-term consequences. Scattered cases involving myopathies, rhabdomyolysis, and compartment syndrome have also been reported throughout the pandemic. Some similar cases have been attributed to systemic capillary leak syndrome (SCLS). Here, we report the development of compartment syndrome involving all extremities in a 57-year-old vaccinated female known to have COVID-19

Cancer therapy-associated Takotsubo cardiomyopathy: A narrative review of mechanisms, drug associations, and clinical implications.

Anticancer therapies have been increasingly associated with Takotsubo cardiomyopathy (TTC). As prior reports remain fragmented across case studies and drug-specific reviews, this paper offers one of the most comprehensive reviews to date of cancer therapy-associated TTC. While classically triggered by emotional or physical stress, TTC has been increasingly associated with chemotherapy and other cancer-directed therapies. This literature review explores the pathophysiology, clinical features, and evolving evidence linking anticancer agents to TTC, with a focus on cytotoxic cancer therapy, hormo

Left Ventricular Hypertrophy: Etiology-Based Therapeutic Options.

Determining the etiologies of left ventricular hypertrophy (LVH) can be challenging due to the similarities of the different manifestations in clinical presentation and morphological features. Depending on the underlying cause, not only left ventricular mass but also left ventricular cavity size, or both, may increase. Patients with LVH remain asymptomatic for a few years, but disease progression will lead to the development of systolic or diastolic dysfunction and end-stage heart failure. As hypertrophied cardiac muscle disrupts normal conduction, LVH predisposes to arrhythmias. Distinguishin

Endothelial activation and stress index is a reliable predictor for the prevalence and mortality outcomes of stroke.

The endothelial activation and stress index (EASIX) can predict endothelial intricacies as well as survival in distinct clinical circumstances. Accordingly, we hypothesize that EASIX may also serve as a predictor for stroke prevalence and mortality outcomes-all-cause mortality (ACM) and cardiovascular mortality (CVM) due to stroke. To validate our hypothesis, we deployed the National Health and Nutrition Examination Survey data. This cohort study employed 1999-2018 NHANES data. To evaluate EASIX effects on stroke risk, weighted logistic regression models were deployed. Meanwhile, we utilized t
