Despite increasing evidence on the benefits of statin therapy for acute myocardial infarction (AMI), differential outcomes in accordance with statin intensity have not been evaluated in patients with AMI and low-density lipoprotein cholesterol (LDL-C) levels < 55 mg/dL. Therefore, this study aimed to compare the clinical outcomes of high- and moderate-intensity statin therapy in this population.

Mounting evidence suggests an associated between myocardial bridging (MB) and coronary vasospasm (CVS); however, no consensus has been established on whether CVS worsens clinical outcomes in patients with MB. Therefore, this retrospective study aimed to compare the long-term clinical outcomes in patients with MB based on CVS presence.

The aim of the study was to analyze the potential relationship between the diuretic response, the clinical profile and the concentrations of selected biochemical markers and to identify a group of patients who will benefit from a new form of therapy combining standard diuretic therapy with the use of a RenalGuard® system.

Mitral regurgitation (MR) is the second most common valvular disease. Symptomatic MR is associated with a poor prognosis. Cardiac surgery is recommended in the severe form of the disease. If the surgical risk is high or functional mitral regurgitation repair/replacement cannot be combined with aorto-coronary bypass graft surgery, a transcatheter edge-to-edge valve repair should be considered. Currently, there is no recommended procedure in patients with severe symptomatic MR, high cardiac surgical risk, and low probability of success or contraindications to the percutaneous edge-to-edge treatment. A recent alternative is the mitral valve implantation using a transapical approach or through the interatrial septum. Currently, the only CE-marked transcatheter bioprothesis valve using transapical approach and implanted without extracorporeal circulation support is the Tendyne valve. This paper discusses the safety, clinical efficacy and cost effectiveness of this valve and the size of the target population in Poland. The clinical efficacy was evaluated in a study of 100 patients with severe symptomatic MR. The total 2-year mortality was 39%. The hospitalisation rate due to heart failure decreased from 1.3 events/year prior to the surgery to 0.51. MR was not recorded in 93.2% of the survivors. An economic analysis accounting for the survival, health-related quality of life, and the risk of hospitalisation due to heart failure showed that the Tendyne system is cost-effective compared to pharmacological treatment: the incremental cost-utility ratio equalled 93,324-110,696 PLN, depending on the approach, clearly below the official threshold in Poland. The annual number of eligible patients was estimated at 60.

Silent cerebral ischemic lesions (SCILs) detected by magnetic resonance imaging (MRI) can precede symptomatic stroke, the risk of which is increased five-fold in atrial fibrillation (AF) patients. In our study, we aimed to evaluate the initial incidence of SCILs in the population of patients referred for ablation due to symptomatic AF and to identify possible risk factors.

SARS-CoV-2 infection may lead to myocardial and endothelial damage. The present study sought to characterize the cardiovascular sequel in a large group of consecutive patients admitted for out-patient cardiovascular follow-up after a symptomatic COVID-19 infection.

The diagnosis of acute myocarditis is complex, with cardiac magnetic resonance (CMR) being a recommended diagnostic method. This study aimed to evaluate the real-life use of CMR in the diagnosis of acute myocarditis and to correlate CMR results with the degree of myocardial damage.

Unfolded Protein Response (UPR), endoplasmic reticulum (ER) stress, and inducible nitric oxide synthase (iNOS) overexpression have been found to influence heart failure with preserved ejection fraction (HFpEF) pathogenesis. Their importance in heart failure with reduced ejection fraction (HFrEF) is not entirely established; there is little data involving a detailed comparison between HFpEF and HFrEF from this perspective. This pilot study aimed to compare circulating levels of Glucose-regulated protein 78kDa (GRP78) (ER - stress marker) and all NOS isoforms between both HFpEF and HFrEF and to analyze the correlation between these markers and the clinical characteristics of the patients.

Changes in the management of patients with chronic coronary syndromes (CCS) require continuous monitoring of results of treatment in daily clinical practice. The present study contains a comparison of the clinical characteristics, management, and in-hospital and five-year outcomes of patients with CCS enrolled on the Prospective REgistry of Stable AnGina management and trEatment (PRESAGE).

Alcohol consumption, even in moderate amounts, is associated with complex changes in blood biochemistry, involving abnormalities of many markers affecting cardiovascular risk.
