Abstract
Today, there are many parameters used for cardiovascular risk quantification and to identify many of the high-risk subjects; however, many of them do not reflect reality. Modern personalized medicine is the key to fast and effective diagnostics and treatment of cardiovascular diseases. One step towards this goal is a better understanding of connections between numerous risk factors. We used Factor analysis to identify a suitable number of factors on observed data about patients hospitalized in the East Slovak Institute of Cardiovascular Diseases in Košice. The data describes 808 participants cross-identifying symptomatic and coronarography resulting characteristics. We created several clusters of factors. The most significant cluster of factors identified six factors: basic characteristics of the patient; renal parameters and fibrinogen; family predisposition to CVD; personal history of CVD; lifestyle of the patient; and echo and ECG examination results. The factor analysis results confirmed the known findings and recommendations related to CVD. The derivation of new facts concerning the risk factors of CVD will be of interest to further research, focusing, among other things, on explanatory methods.

Transcriptome-wide association study uncovers the role of essential genes in anthracycline-induced cardiotoxicity. NPJ Genom Med 2021; 6:35.

Abstract
Anthracyclines are highly effective chemotherapeutic agents; however, their clinical utility is limited by severe anthracycline-induced cardiotoxicity (ACT). Genome-wide association studies (GWAS) have uncovered several genetic variants associated with ACT, but the impact of these findings requires further elucidation. We conducted a transcriptome-wide association study (TWAS) using our previous GWAS summary statistics (n = 280 patients) to identify gene expression-related associations with ACT. We identified a genetic association between decreased expression of GDF5 and ACT (Z-score = -4.30, P = 1.70 × 10-5), which was replicated in an independent cohort (n = 845 patients, P = 3.54 × 10-3). Additionally, cell viability of GDF5-silenced human cardiac myocytes was significantly decreased in response to anthracycline treatment. Subsequent gene set enrichment and pathway analyses of the TWAS data revealed that genes essential for survival, cardioprotection and response to anthracyclines, as well as genes involved in ribosomal, spliceosomal and cardiomyopathy pathways are important for the development of ACT.

Abstract
Cardiovascular deaths account for about 40% of all deaths of patients with chronic kidney disease (CKD), particularly those on dialysis, while sudden cardiac death (SCD) might be responsible for as many as 60% of SCD in patients undergoing dialysis. Studies have demonstrated a number of factors occurring in hemodialysis (HD) that could lead to cardiac arrhythmias. Patients with CKD undergoing HD are at high risk of ventricular arrhythmia and SCD since changes associated with renal failure and hemodialysis-related disorders overlap. Antiarrhythmic therapy is much more difficult in patients with CKD, but the general principles are similar to those in patients with normal renal function - at first, the cause of arrhythmias should be found and eliminated. Also the choice of therapy is narrowed due to the altered pharmacokinetics of many drugs resulting from renal failure, neurotoxicity of certain drugs and their complex interactions. Cardiac pacing in elderly patients is a common method of treatment. Assessment of patients’ prognosis is important when deciding whether to implant complex devices. There are reports concerning greater risk of surgical complications, which depends also on the extent of the surgical site. The decision concerning implantation of a pacing system in patients with CKD should be made on the basis of individual assessment of the patient.

Incidence of new cardiovascular events in patients with and without peripheral arterial disease seen in a vascular surgery clinic. Med Sci Monit 2012; 18:CR131-4. [PMID: 22367123 PMCID: PMC3560756 DOI: 10.12659/msm.882517] [Citation(s) in RCA: 8] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 12/13/2022] Open
Abstract
Background To investigate the incidence of death and of new cardiovascular events at long-term follow-up of patients with and without PAD seen in a vascular surgery clinic. Material/Methods We investigated the incidence of death, new stroke/transient ischemic attack, new myocardial infarction, new coronary revascularization, new carotid endarterectomy, new peripheral arterial disease (PAD) revascularization, or at least one of the above outcomes at long-term follow-up of patients with and without PAD followed in a vascular surgery clinic. Results At least one of the above outcomes occurred in 259 of 414 patients (63%) with PAD at 33-month follow-up and in 21 of 89 patients (24%) without PAD at 48-month follow-up (p<0.0001). Death occurred in 112 of 414 patients (27%) with PAD and in 10 of 89 patients (11%) without PAD (p=0.002). Stepwise Cox regression analysis for the time to at least one of the 6 outcomes showed that significant independent risk factors were men (hazard ratio =1.394; 95% CI, 1.072–1.813; p=0.013), estimated glomerular filtration rate (hazard ratio =0.992; 95% CI, 0.987–0.997; p=0.003), and PAD (hazard ratio =3.520; 95% CI, 2.196–5.641; p<0.0001). Stepwise Cox regression analysis for the time to death showed that significant independent risk factors were age (hazard ratio =1.024; 95% CI, 1.000–1.049; p=0.048), estimated glomerular filtration rate (hazard ratio =0.985; 95% CI, 0.974–0.996; p=0.007), and PAD (hazard ratio =2.157; 95% CI, 1.118–4.160; p=0.022). Conclusions Patients with PAD have a significantly higher incidence of cardiovascular outcomes, especially death, new PAD revascularization, and new carotid endarterectomy, than patients without PAD followed in a vascular surgery clinic.

Abstract
The year 2011 was very interesting regarding new studies, trials and guidelines in the field of lipidology, hypertensiology and nephrology. Suffice it to mention the new European Society of Cardiology (ESC)/European Atherosclerosis Society (EAS) guidelines on the management of dyslipidaemias, American College of Cardiology Foundation (ACCF)/American Heart Association (AHA) guidelines on hypertension in the elderly, and many important trials presented among others during the American Society of Nephrology (ASN) Annual Congress in Philadelphia and the AHA Annual Congress in Orlando. The paper is an attempt to summarize the most important events and reports in the mentioned areas in the passing year.
