Healthcare Situation

The review of the existing evidence on the problem of excessive mortality in Russia has demonstrated that the country is at the initial stage of the irreversible depopulation process. The current healthcare situation, in regard to cardiovascular disease (CVD), does not provide much hope for the effectiveness of existing measures for fatal CVD prevention. It is clear that a large-scale focussed analysis of the clinical and organisational limitations of the existing prevention systems is urgently needed. This discussion should be started in the nearest future.

Prognostic Assessment

The use of pharmacotherapy in prevention is aimed at the correction of already existing consequences (pathology), rather than the prevention of causes. The number of multiple known risk factors (RFs) is steadily increasing, which limits their effective control in the real-world practice. On the other hand, focusing only on a limited number of RFs (7–9) leaves plenty of room for error. Causality is a unity of multiple RFs, unique in each individual case. Determining causality with the use of mathematical modelling can facilitate a more reliable prognostic assessment in cardiovascular disease.

Modifiable Risk Factors

Atrial fibrillation is one of the most common arrhythmias, with a significant increase in incidence in recent years. AF is a major cause of stroke, heart failure, sudden cardiac death, and cardiovascular disease. Timely intervention and modification of risk factors increase chance to stop the disease. Aggressive, multilevel prevention tactics are a component of combined treatment, including – in addition to lifestyle changes, anticoagulant therapy, pharmacotherapy and invasive anti-arrhythmic treatment – prevention of cardiovascular diseases, hypertension, ischemia, valvular disease and heart failure.

Cardiovascular disease is a common cause of death and disease in patients with end-stage renal disease (ESRD). Registry data show that 41% of deaths in ESRD patients are due to a variety of cardiovascular causes, such as acute myocardial infarction, congestive heart failure, arrhythmia/sudden cardiac death, and stroke. In the general population, each of these disease entities in isolation can be effectively managed according to evidence from large clinical trials and evidence-based guidelines. However, many of these trials did not include patients with ESRD, limiting the transferability of this evidence to the care of patients on dialysis. To complicate matters, cardiovascular events in ESRD patients are likely augmented from a unique interplay of cardiac risk due to both reduced kidney function and the necessity for artificial renal replacement therapies. In this light, the patient on dialysis is subjected to a series of unique factors: the continued presence of the metabolic perturbations of uremia and the peculiar environment of the dialysis treatment itself. Since the ESRD heart is under a considerable amount of strain due to chronic volume overload, rapid electrolyte and fluid shifts, and accelerated vascular calcification, management can be complex and outcomes multifactorial. In this review, we summarize the current evidence regarding management of acute myocardial infarction, heart failure, sudden cardiac death, and atrial fibrillation. We also address modifiable risk factors related to the dialysis procedure itself and highlight recent randomized controlled trials that included dialysis patients and measured important cardiovascular outcomes.

Objective The aim of the present study was to develop criteria to identify sudden cardiac death (SCD) and estimate population rates of SCD using administrative mortality and hospital morbidity records in Western Australia. Methods Four criteria were developed using place, death within 24 h, principal and secondary diagnoses, underlying and associated cause of death, and/or occurrence of a post mortem to identify SCD. Average crude, age-standardised and age-specific rates of SCD were estimated using population person-linked administrative data. Results In all, 9567 probable SCDs were identified between 1997 and 2010, with one-third aged ≥35 years having no prior admission for cardiovascular disease. SCD was more frequent in men (62.1%). The estimated average annual crude SCD rate for the period was 34.6 per 100 000 person-years with an average annual age-standardised rate of 37.8 per 100 000 person-years. Age-specific standardised rates were 1.1 per 100 000 person-years and 70.7 per 100 000 person-years in people aged 1–34 and ≥35 years, respectively. Ischaemic heart disease (IHD) was recorded as the underlying cause of death in approximately 80% of patients aged ≥35 years, followed by valvular heart disease and heart failure. IHD was the most common cause of death in those aged 1–34 years, followed by unspecified cardiomyopathy and dysrhythmias. Conclusions Administrative morbidity and mortality data can be used to estimate rates of SCD and therefore provide a suitable methodology for monitoring SCD over time. The findings highlight the magnitude of SCD and its potential for public health prevention. What is known about the topic? There is considerable variability in rates of SCD worldwide. Different data sources and varied methods of case ascertainment likely contribute to this variation. What does this paper add? The rate of SCD in Australia is low compared with international estimates from USA, Ireland, Netherlands and China. Two in every three cases of SCD aged ≥35 years had a hospitalisation history of cardiovascular disease, highlighting the opportunity for prevention. What are the implications for practitioners? High-quality person-linked administrative hospital morbidity and registered mortality data can be used to estimate rates of SCD in the population. Understanding the magnitude and distribution of SCD is imperative for developing effective public health policy and prevention measures.

Background: In hospital-based studies and in studies of participants with pre-existing conditions, African Americans have a higher risk of in- and out-of-hospital sudden cardiac death (SCD) compared with Whites. However, the risk of SCD of African Americans and Whites has never been compared in large-scale community-based cohort studies. Objective: To compare the risk of SCD among African Americans and Whites, and to evaluate the risk factors that may explain racial differences in incidence. Methods: Cohort study of 3,838 African Americans and 11,245 Whites participating in ARIC. Race was self-reported. SCD cases were defined as a sudden pulseless condition from a cardiac cause in a previously stable individual and adjudicated by an expert committee. Mediation effect of covariates was calculated using boot-strapping method. Cox proportional hazards models were adjusted for demographics, social economic status, cardiovascular (CVD), and electrocardiographic risk factors. Results: The mean (SD) age was 53.6 (5.8) for African Americans and 54.4 (5.7) years for Whites. During 25.3 years of follow-up, 215 African Americans and 332 Whites experienced SCD. In multivariable-adjusted models, the HRs (95% CI) for SCD comparing African Americans and Whites were 1.70 (1.37, 2.10) overall, 2.00 (1.40, 2.84) in women, and 1.46 (1.10, 1.92) in men (p-value for race by sex interaction 0.02; Table ). CVD and electrocardiographic risk factors explained 36.6% (21.4, 51.8%) of the excess risk of SCD in African Americans, with a large proportion of racial differences unexplained. Conclusions: The risk of SCD in community-dwelling African Americans was significantly higher than in Whites, particularly among women. CVD risk factors, including higher prevalence of obesity, diabetes, hypertension and LV hypertrophy in African Americans, explained only a small fraction of this difference. Further research is needed to identify factors responsible for race differences in SCD and to implement prevention strategies in high-risk minorities.

Abstract Aim The subcutaneous ICD (S-ICD) has evolved to a potential first option for many patients who have to be protected from sudden cardiac death. Many trials have underlined a similar performance regarding its effectiveness in relation to transvenous ICDs and have shown the expected benefits concerning infective endocarditis and lead failure. However, there have also been problems due to the peculiarities of the device, such as oversensing and myopotentials. In this study, we present patients from a large tertiary centre suffering from complications with an S-ICD and propose possible solutions. Methods and results All S-ICD patients who experienced complications related to the device (n = 40) of our large-scale single-centre S-ICD registry (n = 351 patients) were included in this study. Baseline characteristics, complications occurring and solutions to these problems were documented over a mean follow-up of 50 months. In most cases (n = 23), patients suffered from oversensing (18 cases with T wave or P wave oversensing, 5 due to myopotentials). Re-programming successfully prevented further oversensing episode in 13/23 patients. In 9 patients, generator or lead-related complications, mostly due to infectious reasons (5/9), occurred. Further problems consisted of ineffective shocks in one patient and need for antibradycardia stimulation in 2 patients and indication for CRT in 2 other patients. In total, the S-ICD had to be extracted in 10 patients. 7 of them received a tv-ICD subsequently, 3 patients refused re-implantation of any ICD. One other patient kept the ICD but had antitachycardic therapy deactivated due to inappropriate shocks for myopotential oversensing. Conclusion The S-ICD is a valuable option for many patients for the prevention of sudden cardiac death. Nonetheless, certain problems are immanent to the S-ICD (limited re-programming options, size of the generator) and should be addressed in future generations of the S-ICD. Graphic abstract

Increased Risk

Hypertrophic cardiomyopathy, the most common inherited cardiomyopathy is well known to be the leading cause of sudden cardiac death in young people. However, amongst the population of patients, a small subset bears increased risk of sudden cardiac death and would benefit from implantation of a defibrillator, currently recognized utilizing a series of established risk factors. This risk stratification model is hampered by low positive predictive value. Therefore, novel predictors of sudden death are sought. The advent of cardiac magnetic resonance and late gadolinium enhancement has allowed accurate quantification of regional fibrosis, a key element of hypertrophic cardiomyopathy, pathophysiologically linked to increased arrhythmogenicity. We sought to review currently available data on the utility of late gadolinium enhancement to serve as a novel predictor of arrhythmias and sudden death. In conclusion, significantly diverse methodological approaches and subsequent findings between available studies on the topic have hampered such use, highlighting the need for uniformly designed large scale, prospective studies in order to clarify which aspects of myocardial fibrosis could serve as predictors of arrhythmic events.
