Long-term exposure to antihypertensive drugs and the risk of cancer occurrence: evidence from a large population-based study.

Objective: Available data on the association between antihypertensive drugs and cancer are characterized by a few years follow-up. Our aim has been to evaluate the association between long-term exposure to antihypertensive drugs and the risk of cancer occurrence.

Methods: Using the healthcare utilization databases of the Lombardy region (Italy), individuals aged 40-85 years who had no previous history of cancer and were newly dispensed with at least one antihypertensive drug from the major drug classes between 2009 and 2011 were followed from the first drug dispensation to December 31, 2020.

Troponin T is a better predictor than creatine kinase-MB of long-term mortality after coronary artery bypass graft surgery.

Background: Elevations of creatine kinase-MB (CK-MB) and cardiac troponin T (cTnT) have an uncertain long-term prognostic value after coronary artery bypass graft (CABG) surgery. We aimed to test the hypothesis that CK-MB and cTnT are predictors of long-term survival after CABG and to assess which of these 2 biomarkers is the better predictor.

Methods: A total of 1,350 consecutive patients undergoing isolated on-pump CABG had CK-MB and cTnT measured at 7, 20, and 44 hours, postoperatively.

Effects on plasma noradrenaline may explain some of the improved insulin sensitivity seen by AT-1 receptor blockade.

Aims: We have previously found improved insulin sensitivity in hypertensives after additional treatment with angiotensin II-receptor blocker (ARB) compared with calcium-channel blocker (CCB) alone, despite similar blood pressure lowering effects. In this study, we compare the effect of these two principal different vasodilating agents on the autonomic nervous system in the same patients, and test whether potential differences in these variables might explain the difference seen in insulin sensitivity.

Methods: In a double-blind crossover study, 21 hypertensive patients were randomized to receive either 100 mg losartan (ARB) or 5 mg amlodipine (CCB) in addition to an open-labelled treatment of amlodipine 5 mg.

Impact of new-onset diabetes mellitus on development of atrial fibrillation and heart failure in high-risk hypertension (from the VALUE Trial).

Hypertension and diabetes mellitus (DM) are known risk factors for atrial fibrillation (AF). We investigated the influence of new-onset DM on developing AF in the VALUE trial population of high-risk hypertensive patients. Five thousand two hundred fifty patients of the 15,245 participants in the VALUE trial had DM at baseline and 1,298 of the initially nondiabetic patients developed DM during the average 4.

Complications of hypertension and the role of angiotensin receptor blockers in hypertension trials.

Hypertension is a high-prevalence disease that may affect several organs. In recent years, data have accumulated indicating that angiotensin II receptor blockers (ARBs) may have a supplementary effect beyond lowering blood pressure. The aim of this review is to evaluate the impact of ARBs on the most important complications of hypertension--heart, cerebrovascular and renal diseases, and metabolic complications--based on the findings from large clinical hypertension trials.

Decreased levels of asymmetric dimethylarginine during acute hyperinsulinemia.

Endothelial dysfunction is reflected by an impaired nitric oxide (NO)-mediated vasodilatation. Insulin resistance may be linked to endothelial dysfunction by several mechanisms, including disturbances in signaling pathways common to both insulin action and NO production. Asymmetric dimethylarginine (ADMA), an endogenous inhibitor of NO synthase, may contribute to endothelial dysfunction, and elevated ADMA levels have been associated with both insulin levels and the degree of insulin resistance.

Personality may influence reactivity to stress.

Background: Possible mechanisms behind psychophysiological hyperreactivity may be located at a cognitive-emotional level. Several personality traits have been associated with increased cardiovascular reactivity. Subjects with white coat hypertension, which may constitute a kind of hyperreactivity, are found to suppress their emotions and adapt to the surroundings to a larger extent than controls.

N-terminal pro-B-type natriuretic peptide in risk stratification after acute myocardial infarction in patients on long-term beta-adrenergic receptor blocker therapy.

Background: N-terminal pro-B-type natriuretic peptide (NT-proBNP) appears to be a strong risk marker of mortality in patients with acute coronary syndrome. However, little information is available on NT-proBNP as a predictor of long-term serious cardiovascular events beyond that of left ventricular ejection fraction in patients with acute myocardial infarction (AMI), most of them treated with an early invasive strategy and on a uniform optimal secondary preventive medication including long-term beta-adrenergic receptor blockade.

Objective: To assess the prognostic impact of plasma NT-proBNP in patients with AMI who received optimal medical treatment including long-term beta-adrenergic receptor blockade.
