Fatal Left Ventricular Free Wall Rupture Complicating Acute Myopericarditis.

This is a case of a 59-year-old man presenting with myopericarditis. Over a 2-week period, he developed progressive symptoms and worsening pericardial effusion, leading to cardiac tamponade. Pericardiocentesis revealed hemopericardium, and multidetector computed tomography angiography showed left ventricular free wall rupture. The patient collapsed abruptly, and autopsy confirmed the findings.

The Associations between Kidney Function and Sexual Dysfunction among Males and Females with Type 2 Diabetes Mellitus.

Background and Objectives: Diabetic kidney disease (DKD), expressed either as albuminuria, low estimated glomerular filtration rate (eGFR) or both, and sexual dysfunction (SD), are common complications among type 2 diabetes mellitus (T2DM) patients. This study aims to assess whether an association exists between DKD and SD, erectile dysfunction (ED) or female sexual dysfunction (FSD) in a T2DM population. Materials and Methods: A cross-sectional study was designed and conducted among T2DM patients. The presence of SD was assessed using the International Index of Erectile Function and the Female Sexual Function Index questionnaires for males and females, respectively, and patients were evaluated for DKD. Results: Overall, 80 patients, 50 males and 30 females, agreed to participate. Sexual dysfunction was present in 80% of the study population. Among the participants, 45% had DKD, 38.5% had albuminuria and/or proteinuria and 24.1% had an eGFR below 60 mL/min/1.73 m2. The eGFR was associated with SD, ED and FSD. Moreover, SD and ED were proven as significant determinants for lower eGFR values in multiple linear regression analyses. DKD was associated with lower lubrication scores and eGFR was associated with lower desire, arousal, lubrication and total scores; however, the multivariate linear regression analyses showed no significant associations between them. Older age resulted in significantly lower arousal, lubrication, orgasm and total FSFI scores. Conclusions: SD is commonly encountered in older T2DM patients and DKD affects almost half of them. The eGFR has been significantly associated with SD, ED and FSD, while SD and ED were proven to be significant determinants for the eGFR levels.

Hypertension in Pregnancy: Unanswered Questions.

BACKGROUND: Hypertension of pregnancy [office blood pressure (BP) levels≥140/90 mmHg] is fairly common and can affect up to 10% of pregnant women worldwide. Hypertension of pregnancy is an important risk factor for the mother and carries increased morbidity and mortality for the fetus. Women with hypertension of pregnancy have a high-risk for future cardiovascular and renal events. OBJECTIVES: To summarize the literature related to several clinical aspects of hypertension in pregnancy and draw clinically meaningful conclusions. METHODS: We conducted an in-depth review of the literature to retrieve existing data on the definition, epidemiology, classification, and management of hypertension in pregnancy. RESULTS: All pregnant women with hypertension should have a proper diagnostic workup and be treated appropriately. In women with mild hypertension, BP therapeutic target should be set to 110-140/80-85mmHg. In women with severe hypertension, BP should be reduced by at least 25% as soon as possible, and gradually thereafter to normal target levels of <140/105mmHg. In terms of preeclampsia, physicians need to consider potential complications and formulate prevention strategies. The choice of antihypertensive medication is crucial since certain classes can be detrimental to the fetus and should be avoided. Post-partum, the choice of antihypertensive therapy of the mother should take into consideration breastfeeding of the fetus. Given the life-long cardiovascular risk of women with pregnancy hypertension, a regular cardiovascular evaluation is in order. CONCLUSION: Albeit the antihypertensive treatment exerts significant benefits for both the mother and the baby, several clinical aspects remain un-tackled. More research is needed to further improve the treatment of such disorders.

Risk Scores and Prediction Models in Chronic Heart Failure: A Comprehensive Review.

BACKGROUND: Heart failure affects a substantial proportion of the adult population, with an estimated prevalence of 1-2% in developed countries. Over the previous decades, many prediction models have been introduced for this specific population in an attempt to better stratify and manage heart failure patients. OBJECTIVE: The aim of this study is the systematic review of recent, relevant literature regarding risk scores or prediction models in ambulatory patients with an established diagnosis of chronic heart failure. METHODS: We conducted a systematic search of the literature in PubMed and CENTRAL from their inception up till December 2019 for studies assessing the performance of risk scores and prediction models and original research studies. Grey literature was searched as well. This review is reported in accordance with the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) statement. RESULTS: We included 16 eligible studies in this systematic review. Major heart failure risk scores derived from large heart failure populations were among the included studies. Due to significant heterogeneity regarding the main endpoints, a direct comparison of the included prediction scores was inevitable. The majority referred to patients with heart failure with reduced ejection fraction, while only two out of 16 prediction scores have been developed exclusively for heart failure patients with preserved ejection fraction. Ischemic heart disease was the most common aetiology of heart failure in the included studies. Finally, more than half of the prediction scores have not been externally validated. CONCLUSION: Prediction models aiming at heart failure patients with a preserved or mid-range ejection fraction are lacking. Prediction scores incorporating recent advances in pharmacotherapy should be developed in the future.

Colchicine as a Potential Therapeutic Agent Against Cardiovascular Complications of COVID-19: an Exploratory Review.

Coronavirus disease-19 (COVID-19) may result in serious complications involving several organ systems, including myocardial tissue. An exaggerated host inflammatory response, described as a cytokine storm, has been linked to play a major role in these complications. Colchicine and other pharmaceutical agents have been proposed to counter the cytokine storm and improve outcomes. In this exploratory review, we utilized a PubMed and Cochrane Database search aiming to identify the biochemical characteristics of the cytokine storm as well as to identify the potential effect of colchicine on these inflammatory biomarkers. The research yielded 30 reports describing the characteristics of the cytokine storm and 44 reports describing the effect of colchicine on various inflammatory biomarkers. According to our research, colchicine may be an agent of interest in the treatment of COVID-19 via its anti-inflammatory properties. However, there are potential drug interactions with cytochrome P450 3A4 inhibitors resulting in acute colchicine toxicities. Additionally, there is scarce evidence regarding the efficacy of colchicine in the acute phase of disease, since most trials evaluated its effect in chronic conditions. In this direction, our team proposes three different hypotheses for evaluating the place of colchicine in the treatment of COVID-19.

Evaluation of the Irradiated Volume of the Heart and Cardiac Substructures After Left Breast Radiotherapy.

Backround/Aim: Adjuvant radiotherapy in patients with cancer of the left breast may lead to impaired cardiac function. The aim of our prospective study is to evaluate (i) doses to the irradiated volume of the heart and its substructures and (ii) determine whether their correlation with changes in strain echo measurements contribute to the prediction of subclinical heart morbidity. PATIENTS AND METHODS: Twenty-five patients were enrolled in our study. We retrospectively assessed the radiation doses to the whole heart, left anterior descending artery (LAD) and left ventricle (LV). RESULTS: The mean heart dose (MHD) was 152 cGy (SD=50.56 cGy) and the range was 74-279 cGy. The LAD was the most exposed structure, with a mean dose of 448.91 cGy (SD=490.53 cGy) and range of 120-2,057cGy. Finally, the mean LV dose was 149.12 cGy (SD=69.57) with a range of 63-317 cGy. CONCLUSION: The early results of our study showed low radiation exposure of the whole heart and left ventricle, and higher exposure of the LAD. The data that will emerge from the evaluation of strain echo parameters should show whether these associations might be useful in clinical practice for the prediction of early subclinical cardiac changes.

Macrovascular Complications of Type 2 Diabetes Mellitus.

BACKGROUND: Type 2 diabetes mellitus (T2DM) has emerged as a pandemic. It has different complications, both microvascular and macrovascular. OBJECTIVE: The purpose of this review is to summarize the different types of macrovascular complications associated with T2DM. METHODS: A comprehensive review of the literature was performed to identify clinical studies, which determine the macrovascular complications associated with T2DM. RESULTS: Macrovascular complications of T2DM include coronary heart disease, cardiomyopathy, arrhythmias and sudden death, cerebrovascular disease and peripheral artery disease. Cardiovascular disease is the primary cause of death in diabetic patients. Many clinical studies have shown a connection between T2DM and vascular disease, but almost always other risk factors are present in diabetic patients, such as hypertension, obesity and dyslipidaemia. CONCLUSION: T2DM causes a variety of macrovascular complications through different pathogenetic pathways that include hyperglycaemia and insulin resistance. The association between T2DM and cardiovascular disease is clear, but we need more clinical studies in order to identify the pure effect of T2DM.

Lung Ultrasound-Guided Dry-Weight Reduction in Hemodialysis Patients Does Not Affect Short-Term Blood Pressure Variability.

BACKGROUND: Increased short-term blood pressure (BP) variability (BPV) in hemodialysis is associated with increased cardiovascular and all-cause mortality. Studies on the impact of BP-lowering interventions on BPV are scarce. This study examined the effect of dry-weight reduction with a lung ultrasound-guided strategy on short-term BPV in hemodialysis patients with hypertension. METHODS: This is a prespecified analysis of a randomized clinical trial in 71 hemodialysis patients with hypertension, assigned in a 1:1 ratio in the active group, following a strategy for dry-weight reduction guided by pre-hemodialysis lung ultrasound and the control group following standard-of-care treatment. All patients underwent 48-hour ambulatory BP monitoring at baseline and after 8 weeks. BPV was calculated with validated formulas for the 48-hour interval and the 2 daytime and nighttime periods. RESULTS: Dry-weight changes were -0.71 ± 1.39 in active vs. +0.51 ± 0.98 kg in the control group (P < 0.001), generating a between-group difference of 5.9/3.5 mm Hg (P < 0.05) in 48-hour BP at study end. All brachial BPV indices [SD, weighted SD, coefficient of variation, and average real variability (ARV)] did not change significantly from baseline to study end in the active [systolic blood pressure (SBP)-ARV: 12.58 ± 3.37 vs. 11.91 ± 3.13, P = 0.117; diastolic blood pressure (DBP)-ARV: 9.14 ± 1.47 vs. 8.80 ± 1.96, P = 0.190] or control (SBP-ARV: 11.33 ± 2.76 vs. 11.07 ± 2.51, P = 0.544; DBP-ARV: 8.38 ± 1.50 vs. 8.15 ± 1.49, P = 0.295) group (between-group comparison P = 0.211/0.117). Aortic BPV indices followed a similar pattern. Likewise, no significant changes in BPV indices for the daytime and nighttime periods were noted in both groups during follow-up. CONCLUSIONS: This study is the first to evaluate the effects of a nonpharmacological intervention on short-term BPV in hemodialysis, showing no effect of dry-weight reduction on BPV, despite BP decrease.
