    Heart failure has become a major public health problem. About 2-3% of people over 65 years suffer from Heart Failure. A huge amount of money is spent every year treating problems connected with this syndrome. In this paper we analyse randomised prospective trials which support the use of beta-blockers in these patients. We also analyse the benefits of this treatment and some special considerations concerning the use of these drugs

    In the last few years, the evolution of coronary interventionism has been very important. The primary success rates in the early 1990s were 86-88% with a re-stenosis rate of 30%-40%. Current primary success rates have risen to over 95% with a re-stenosis rate of under 10% even for many types of lesions classically considered complex. Currently the main limitations in interventional cardiology remain coronary segments that cannot be accessed due to chronic total occlusion, or severe proximal tortuosity or calcification. Rapid improvements have led to broader clinical indications for percutaneous revascularization procedures. We describe the latest improvements in technique

    Background Real-world data on non-vitamin K oral anticoagulants (NOACs) are essential in determining whether evidence from randomised controlled clinical trials translate into meaningful clinical benefits for patients in everyday practice. RIVER (RIVaroxaban Evaluation in Real life setting) is an ongoing international, prospective registry of patients with newly diagnosed non-valvular atrial fibrillation (NVAF) and at least one investigator-determined risk factor for stroke who received rivaroxaban as an initial treatment for the prevention of thromboembolic stroke. The aim of this paper is to describe the design of the RIVER registry and baseline characteristics of patients with newly diagnosed NVAF who received rivaroxaban as an initial treatment. Methods and results Between January 2014 and June 2017, RIVER investigators recruited 5072 patients at 309 centres in 17 countries. The aim was to enroll consecutive patients at sites where rivaroxaban was already routinely prescribed for stroke prevention. Each patient is being followed up prospectively for a minimum of 2-years. The registry will capture data on the rate and nature of all thromboembolic events (stroke / systemic embolism), bleeding complications, all-cause mortality and other major cardiovascular events as they occur. Data quality is assured through a combination of remote electronic monitoring and onsite monitoring (including source data verification in 10% of cases). Patients were mostly enrolled by cardiologists (n = 3776, 74.6%), by internal medicine specialists 14.2% (n = 718) and by primary care/general practice physicians 8.2% (n = 417). The mean (SD) age of the population was 69.5 (11.0) years, 44.3% were women. Mean (SD) CHADS2 score was 1.9 (1.2) and CHA2DS2-VASc scores was 3.2 (1.6). Almost all patients (98.5%) were prescribed with once daily dose of rivaroxaban, most commonly 20 mg (76.5%) and 15 mg (20.0%) as their initial treatment; 17.9% of patients received concomitant antiplatelet therapy. Most patients enrolled in RIVER met the recommended threshold for AC therapy (86.6% for 2012 ESC Guidelines, and 79.8% of patients according to 2016 ESC Guidelines). Conclusions The RIVER prospective registry will expand our knowledge of how rivaroxaban is prescribed in everyday practice and whether evidence from clinical trials can be translated to the broader cross-section of patients in the real world

    Characteristics of hypertensive cardiomyopathy in a population of hypertensive patients never treated

    BACKGROUND AND OBJECTIVE: Although impaired diastolic function is frequently found in systemic hypertension, the diagnosis of hypertensive heart disease (HHD) is based on the demonstration of left ventricular (LV) growth. The aim of the current work was to investigate the potential interactions between diastolic function and LV growth in patients with arterial hypertension. PATIENTS AND METHOD: One hundred and sixteen never-treated asymptomatic hypertensives underwent an echocardiographic evaluation. Classification of diastolic dysfunction (DD) was based on alterations in parameters assessing transmitral inflow, Doppler tissue imaging of mitral annular motion, and color M-mode propagation velocity. Classification of LV growth was based on alterations in left ventricular mass index and/or relative will thickness. RESULTS: Ninety-four patients (81%) exhibited DD and 22 (19%) exhibited normal diastolic function. Amongst patients with DD, 79 (84%) exhibited a pattern of impaired relaxation and 15 (16%) a pseudonormal pattern. The presence of LV growth was documented in 41% of patients without DD and 75% of patients with DD (p < 0.05). None of the studied patients exhibited echocardiographic signs of systolic dysfunction. CONCLUSIONS: These findings indicate that DD is an early and highly frequent cardiac alteration in arterial hypertension. In addition, our data show that one fifth of hypertensive patients have DD in the absence of LV growth. It is thus suggested that the diagnosis of HHD can not be further based exclusively on morphologic criteria and should include also the evaluation of alterations in LV filling

    Usefulness of plasma cardiotrophin-1 in assessment of left ventricular hypertrophy regression in hypertensive patients

    OBJECTIVE: We investigated whether regression of left ventricular hypertrophy (LVH) in response to antihypertensive treatment is associated with plasma cardiotrophin-1 (CT-1) in hypertensive patients. METHODS: The study was performed in 47 patients with mild to moderate essential hypertension, and LVH was assessed echocardiographically. The family doctor gave antihypertensive treatment and followed all patients. LVH regression was diagnosed if the baseline left ventricular mass index (LVMI) decreased to normal values after 1 year of treatment. Plasma CT-1 was determined by an enzyme-linked immunosorbent assay. RESULTS: The LVMI was normalized in 23 patients (49%) and persisted at an abnormally increased level in 24 patients (51%) after 1 year of treatment, whereas the reduction in clinic and home blood pressure was similar in the two groups: CT-1 decreased (-48%, P < 0.005) and increased (+35%, P < 0.05) in patients in whom LVH regressed and LVH persisted, respectively. Final values of CT-1 were inversely correlated (r = 0.534, P < 0.001) with the decrease in LVMI after treatment in all patients. A significant association (chi2 = 16.87, P < 0.001) was found between normalization of CT-1 and regression of LVH with treatment. A cut-off value of 41 fmol/ml for CT-1 provided a relative risk of 43.13 (95% confidence interval, 4.88-380.48) for detecting LVH regression. CONCLUSION: These results show an association between treatment-induced decrease of plasma CT-1 and LVH regression in essential hypertension. Although preliminary, these findings suggest that the determination of plasma CT-1 may be useful for the follow-up of hypertensive heart disease in routine clinical practice
