The relationship between circulating fibrosis-related molecules and magnetic resonance-assessed cardiac fibrosis in dilated cardiomyopathy (DCM) is poorly understood. To compare circulating biomarkers between DCM patients with high and low fibrosis burdens, we performed a prospective, single-center, observational study. The study population was composed of 100 DCM patients (87 male, mean age 45.

Methods And Results: The hospital and outpatient records of 406 DCM patients were retrospectively analysed. The information on patient status was gathered after 48.
Article Synopsis
- Patients with heart failure and dilated cardiomyopathy (DCM) often experience pulmonary hypertension (PH), which leads to worse health outcomes, but the exact effects of PH on DCM are not well understood.
- The study analyzed the medical records of 502 DCM patients, categorizing them into low, intermediate, and high PH-risk groups based on echocardiography results, and tracked their outcomes over an average of nearly 46 months.
- Findings showed that low PH risk was linked to a significantly lower risk of death compared to high risk, with over 20% of the patients having high PH risk, indicating that PH risk is an important factor in the prognosis of DCM patients.
Article Synopsis
- Atrial fibrillation (AF) is common in patients with dilated cardiomyopathy (DCM), affecting about 31% of studied patients, who tend to be older and have various health issues compared to those without AF.
- During a follow-up period, patients with AF showed a significantly higher rate of death, and AF was identified as an independent negative prognostic factor for DCM outcomes.
- A notable portion (24%) of the patients with DCM and AF were diagnosed with AF-induced DCM, highlighting the complex relationship between the two conditions.
Introduction: An epidemic of syphilis and other sexually transmitted infections (STI) in the Russian Federation is believed to be related to the rise in injection drug use. A study was carried out in collaboration with a non-governmental organization, Foundation 'Vozvrastcheniye'.
Methods: Nine hundred and ten injection drug users participating in the programme were tested for syphilis, HIV, hepatitis C virus (HCV) and hepatitis B virus (HBV); 65 participants who had laboratory markers for syphilis and 45 syphilis-negative serosurvey subjects agreed to participate in a questionnaire study.
