Partial vena cava occlusion (VCO) to counteract refractory heart failure: a new era in interventional heart failure strategy

Background: Patients with acute decompensated heart failure are prone to recurrent exacerbation leading to poor quality of life when they do not respond to an optimal medical regimen. Due to the lack of linear positive inotropy response to increasing preload in heart failure patients, increasing preload is associated with poor outcomes. Partial occlusion of either IVC or SVC is a proposed novel treatment that can improve cardiac function or quality of life by altering preload/pressure in heart failure (HF) patients unresponsive to diuretics. Methods: PubMed, Ovid (MEDLINE), and Cochrane database we searched using the MeSH terms including "Superior vena cava occlusion," "Inferior vena cava occlusion," "Heart failure exacerbation." The inclusion criteria included studies that enrolled patients > 18 years with diagnosed NYHA II-IV HF with reduced ejection fraction (HFrEF) on optimal medical treatment (OMT). Results: The analysis involved two studies with 14 patients; the mean age was 64.4 ± 10 and 100% males. The difference in the mean pulmonary pressures between pre-and-post VCO devices were 1.56 (95% CI 0.66-2.46, p-value = 0.006). There was no heterogeneity among the study of mean pulmonary pressures. With the use of VC occlusion devices, the mean difference in pulmonary artery systolic pressure decreased by 1.70 (95% CI 0.68-2.71, p-value = 0.001) (Fig. 1B). The heterogeneity of mean pressure was minimal 14%. Conclusion: In conclusion, VCO can help decrease pulmonary pressure that can indirectly prevent heart failure exacerbations and possibly hospitalization in this cohort of patients.</p

Clinical and angiographic success and safety comparison of coronary intravascular lithotripsy: an updated meta-analysis

Background: Intravascular lithotripsy (IVL) can be used to assist stent deployment in severe coronary artery calcifications (CAC).Methods: Studies employing IVL for CAC lesions were included. The primary outcomes included clinical and angiographic success. The secondary outcomes, including lumen gain, maximum calcium thickness, and calcium angle at the final angiography site, minimal lumen area site, and minimal stent area site, were analyzed by the random-effects model to calculate the pooled standardized mean difference. Tertiary outcomes included safety event ratios.Results: Seven studies (760 patients) were included. The primary outcomes: pooled clinical and angiographic success event ratio parentage of IVL was 94.4% and 94.8%, respectively. On a random effect model for standard inverse variance for secondary outcomes showed: minimal lumen diameter increase with IVL was 4.68 mm (p-value Conclusions: Evidence suggests that IVL safely and effectively facilitates stent deployment with high angiographic and clinical success rates in treating severely calcified coronary lesions.</div

Long term outcomes of percutaneous coronary intervention vs coronary artery bypass grafting in patients with diabetes mellitus with multi vessels diseases: a meta-analysis

Aims: Long term cardiovascular outcome comparison of multivessel coronary disease among patients with diabetes mellitus (DM) undergoing percutaneous coronary intervention (PCI) or coronary artery bypass graft (CABG) is limited. The objective of this study was to compare the long-term cardiovascular outcome PCI vs CABG among DM patients with multivessel disease.  Method and results: Online databases were explored to identify studies that compared cardiovascular outcomes between PCI and CABG among patients with DM. The primary outcome was all-cause mortality. Secondary outcomes included major adverse cardiovascular and cerebrovascular events (MACCE), myocardial infarction (MI), rate of revascularization, cardiac death, and cerebrovascular accident (CVA). A total of 27 studies with 37,091 (PCI n = 19,838 (53 %) and CABG n = 17,253 (47 %)) patients were included. The mean age was 64 ± 5.9 years for PCI group and 63.8 ± 5.3 years for CABG group; and, predominantly male (71.22 % vs 74.29 %) for PCI and CABG respectively. The most common comorbidity was hypertension (64.35 % vs 62.88 %) in both PCI and CABG respectively. Compared with CABG, PCI group had a higher odds of overall all-cause mortality (OR 1.18, 95 % CI 1.02–1.37, p = 0.03), MACCE (OR 1.52, 95 % CI 1.31–1.75, p = 0.00), MI (OR 1.85, 95 % CI 1.46–2.36, p = 0.00), repeat revascularization (OR 3.08, 95 % CI 2.34–4.05, p = 0.00) and cardiac death (OR 1.27, 95 % 1.02–1.59, p = 0.04), while CVA (0.57, 95 % CI 0.37–0.86, p = 0.01) was higher with CABG.  Conclusion: Diabetic patients with multivessel coronary artery disease have worse outcomes undergoing PCI as compared to CABG. However, CVA was significantly higher with CABG. CABG remains the preferred management among eligible patients with multivessel disease and DM.</p

Diabetes mortality and trends before 25 years of age: an analysis of the Global Burden of Disease Study 2019

Background: Diabetes, particularly type 1 diabetes, at younger ages can be a largely preventable cause of death with the correct health care and services. We aimed to evaluate diabetes mortality and trends at ages younger than 25 years globally using data from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2019. Methods: We used estimates of GBD 2019 to calculate international diabetes mortality at ages younger than 25 years in 1990 and 2019. Data sources for causes of death were obtained from vital registration systems, verbal autopsies, and other surveillance systems for 1990–2019. We estimated death rates for each location using the GBD Cause of Death Ensemble model. We analysed the association of age-standardised death rates per 100 000 population with the Socio-demographic Index (SDI) and a measure of universal health coverage (UHC) and described the variability within SDI quintiles. We present estimates with their 95% uncertainty intervals. Findings: In 2019, 16 300 (95% uncertainty interval 14 200 to 18 900) global deaths due to diabetes (type 1 and 2 combined) occurred in people younger than 25 years and 73·7% (68·3 to 77·4) were classified as due to type 1 diabetes. The age-standardised death rate was 0·50 (0·44 to 0·58) per 100 000 population, and 15 900 (97·5%) of these deaths occurred in low to high-middle SDI countries. The rate was 0·13 (0·12 to 0·14) per 100 000 population in the high SDI quintile, 0·60 (0·51 to 0·70) per 100 000 population in the low-middle SDI quintile, and 0·71 (0·60 to 0·86) per 100 000 population in the low SDI quintile. Within SDI quintiles, we observed large variability in rates across countries, in part explained by the extent of UHC (r2=0·62). From 1990 to 2019, age-standardised death rates decreased globally by 17·0% (−28·4 to −2·9) for all diabetes, and by 21·0% (–33·0 to −5·9) when considering only type 1 diabetes. However, the low SDI quintile had the lowest decline for both all diabetes (−13·6% [–28·4 to 3·4]) and for type 1 diabetes (−13·6% [–29·3 to 8·9]). Interpretation: Decreasing diabetes mortality at ages younger than 25 years remains an important challenge, especially in low and low-middle SDI countries. Inadequate diagnosis and treatment of diabetes is likely to be major contributor to these early deaths, highlighting the urgent need to provide better access to insulin and basic diabetes education and care. This mortality metric, derived from readily available and frequently updated GBD data, can help to monitor preventable diabetes-related deaths over time globally, aligned with the UN's Sustainable Development Targets, and serve as an indicator of the adequacy of basic diabetes care for type 1 and type 2 diabetes across nations.
