Aims: Current guidelines recommend serial echocardiography at minimum 1-2 year intervals for monitoring patients with nonsevere aortic valve stenosis (AS), which is costly and often clinically inconsequential.We aimed to develop and test whether the biomarker-based ASGARD risk score (Aortic Valve Stenosis Guarded by Amplified Risk Determination) can guide the timing of echocardiograms in asymptomatic patients with nonsevere AS.
Methods: The development cohort comprised 1,093 of 1,589 (69%) asymptomatic patients with mild-to-moderate AS who remained event-free one year after inclusion into the SEAS trial.
More than 90 % of patients developing heart failure (HF) have hypertension. The most frequent concomitant conditions are type-2 diabetes mellitus, obesity, atrial fibrillation, and coronary disease. HF outcome research focuses on decreasing mortality and preventing hospitalization for worsening HF syndrome.

The most frequent concomitant conditions are type 2 diabetes mellitus, obesity, atrial fibrillation, and coronary disease, all disorders/diseases closely related to hypertension.
Methods: HF outcome research focuses on decreasing mortality and preventing hospitalization for worsening HF syndrome.
Background: Approximately 40% of people with hypertension have left ventricular hypertrophy (LVH) detected by ECG or echocardiography. Because patients with LVH have poor myocardial microcirculation, they may be too sensitive to lowering systolic blood pressure (SBP) too much due to a lack of myocardial perfusion pressure. We aimed to investigate whether the average achieved SBP <130 mm Hg may cause harm in patients with LVH in the Valsartan Antihypertensive Long-Term Use Evaluation trial (VALUE).

However, its prognostic value remains unknown in asymptomatic patients with AS. We aimed to investigate if an hsTnT level >14 pg/mL (above upper limit of normal 99th percentile) is associated with echocardiographic AS-severity, subsequent AVR, ischaemic coronary events (ICE), and mortality in asymptomatic patients with non-severe AS.

Adding a reliable cardiac biomarker to the exercise test could potentially improve the precision of the test. We investigated circulating NT-proBNP levels before and during exercise stress test in patients with and without angiographically verified CAD.

The purpose of this study was to evaluate the use of a new multivariate predictive model to identify AoR dilatation in hypertensive patients with left ventricular hypertrophy.
Methods: 943 of 961 patients in the Losartan Intervention For Endpoint reduction in hypertension (LIFE) echocardiographic sub-study had the necessary baseline characteristics and echocardiographic 2D measurements of AoR size to be included.

Importance: Recent studies have questioned the presumed low-risk status of patients with asymptomatic nonsevere aortic stenosis (AS). Whether annual N-terminal pro-brain natriuretic peptide (NT-proBNP) measurements are useful for risk assessment is unknown.
Objective: To assess the association of annual NT-proBNP measurements with clinical outcomes in patients with nonsevere AS.
Hypertension constitutes a major risk factor for heart failure with preserved ejection fraction (HFpEF). HFpEF is a prevalent clinical syndrome with increased cardiovascular morbidity and mortality. Specific guideline-directed medical therapy (GDMT) for HFpEF is not established due to lack of positive outcome data from randomized controlled trials (RCTs) and limitations of available studies.

We examined if hyponatremia heralds poor prognosis in patients with asymptomatic AS, and whether AS in itself is associated with increased risk of hyponatremia. The study question was investigated in 1,677 individuals that had and annual plasma sodium measurements in the SEAS (Simvastatin and Ezetimibe in AS) trial; 1,873 asymptomatic patients with mild-moderate AS (maximal transaortic velocity 2.

Methods: Of the 1873 patients included in SEAS, 1849 (99%) with mild to moderate AS (jet velocity 2.5-4.
: Hypertensive patients are at increased risk of atrial fibrillation (AF). Although low baseline high density lipoprotein (HDL) cholesterol has been associated with a higher risk of AF, this has not been verified in recent population-based studies. Whether changing levels of HDL over time are more strongly related to the risk of new AF in hypertensive patients has not been examined.

Methods: We systematically collated data from randomized, controlled trials. cIMT was assessed as the mean value at the common-carotid-artery; if unavailable, the maximum value at the common-carotid-artery or other cIMT measures were used.
Current cardiovascular pharmacotherapy targets maladaptive overactivation of the renin-angiotensin-aldosterone system (RAAS), which occurs throughout the continuum of cardiovascular disease spanning from hypertension to heart failure with reduced ejection fraction. Over the past 16 years, 4 prospective, randomized, placebo-controlled clinical trials using candesartan, perindopril, irbesartan, and spironolactone in patients with heart failure with preserved ejection fraction (HFpEF) failed to demonstrate increased efficacy of RAAS blockade added to guideline-directed medical therapy. We reappraise these trials and their weaknesses, which precluded statistically significant findings.

We used 1,687 patients with asymptomatic mild-to-moderate AS, who were randomly assigned (1:1) to 40/10 mg simvastatin/ezetimibe combination versus. placebo in the simvastatin and ezetimibe in aortic stenosis (SEAS) trial.
View Article and Find Full Text PDFAtrial fibrillation (AF) is associated with increased cardiovascular risk and the incidence increases with age, hypertension and left ventricular hypertrophy (LVH). Reducing in-treatment systolic blood pressure (SBP) prevents new-onset AF but has previously not been studied in patients with isolated systolic hypertension (ISH). We aimed to investigate the effect on preventing new-onset AF by decreased in-treatment SBP in patients with ISH compared to patients with non-ISH.

This paper describes the rationale and design of the randomized trial, in addition to the baseline characteristics of the population screened and enrolled so far.
Methods: The DanGer Shock study is a prospective, multicenter, open-label trial in patients with AMICS randomized 1:1 to Impella CP or current guideline-driven therapy with planned enrollment of 360 patients.
Background: Exercise stress test (EST) has a moderate precision for diagnosis of CAD and could potentially obtain improved accuracy if adding a reliable cardiac biomarker to the test.
Objective: We aimed to investigate resting levels and change in hs-cTnT during EST in patients with and without angiographically significant CAD. Moreover, we intended to explore the additive value of hs-cTnT to EST results in diagnosis of stable CAD.
Aims: We aimed to investigate whether left bundle branch block (LBBB) is related to new-onset left ventricle (LV) wall motion abnormalities during treatment in hypertensive patients with electrocardiographic (ECG) defined left ventricular hypertrophy (LVH).
Methods And Results: 960 patients with essential hypertension and ECG-LVH participating in the LIFE Echo Sub-study were investigated at baseline and annually with echocardiography, during randomized antihypertensive therapy. After excluding patients with LV wall motion abnormalities at baseline and patients developing new-onset LBBB during study time, we investigated 784 patients.
