Background
Coronavirus disease 2019 (COVID-19) has led to a widespread morbidity and mortality. Limited data exists regarding the involvement of cardiovascular system in COVID-19 patients. We sought to evaluate the cardiovascular (CV) complications and its impact on outcomes in symptomatic COVID-19 patients.
Methods
This was a single center observational study among symptomatic COVID-19 patients. Data regarding clinical profile, laboratory investigations, CV complications, treatment and outcomes were collected. Cardiac biomarkers and 12 lead electrocardiograms were done in all while echocardiography was done in those with clinical indications for the same. Corrected QT-interval (QTc) at baseline and maximum value during hospitalization were computed.
Results
Of the 108 patients, majority of them were males with a mean age of 51.2 ± 17.7 years. Hypertension (38%) and diabetes (32.4%) were most prevalent co-morbidities. ECG findings included sinus tachycardia in 18 (16.9%), first degree AV block in 5 (4.6%), VT/VF in 2 (1.8%) and sinus bradycardia in one (0.9%). QTc prolongation was observed in 17.6% subjects. CV complications included acute cardiac injury in 25.9%, heart failure, cardiogenic shock and acute coronary syndrome in 3.7% each, “probable” myocarditis in 2.8% patients. Patients with acute cardiac injury had higher mortality than those without (16/28 [57.1%] vs 14/78 [17.5%]; P < 0.0001). Multivariate logistic regression analysis showed that acute cardiac injury (OR: 11.3), lymphopenia (OR: 4.91), use of inotropic agents (OR: 2.46) and neutrophil-lymphocyte ratio (OR:1.1) were independent predictors of mortality.
Conclusions
CV complications such as acute cardiac injury is common in COVID-19 patients and is associated with worse prognosis.
Internal jugular (IJ) catheter insertion for hemodialysis (HD) is an indispensable procedure in the management of patients with renal failure. The central approach is favored over posterior approach to insert IJ catheters. There are no studies comparing the outcomes between the two approaches. The aim of this study was to compare central approach with posterior approach for IJ HD catheter insertion and to analyze various outcomes like procedure-related complication rates, catheter insertion failure rates, interruptions during dialysis due to blood flow obstruction and catheter infection rates between the two methods among patients receiving HD. All patients requiring IJ HD catheter insertion during a 1-month period were randomly assigned to undergo catheter insertion via either conventional central approach or posterior approach. Patients were followed-up till the removal of the catheter. Among 104 patients included in the study, 54 were assigned to the central approach group and 50 to the posterior approach group. The central approach group had higher rate of procedure-related complications (14.81% vs. 6%, P = 0.04). Catheter insertion failure rates were marginally higher in posterior approach group (20% vs. 12.96%, P = 0.07). One or more instance of interruption during HD due to obstruction in blood flow was more common in posterior approach (46% vs. 9.25%, P < 0.01). Catheter infection rates were similar between the two groups; 16.66% (n = 9) in central group vs. 14% (n = 7) in posterior group. Posterior approach is a reasonable alternative to conventional central approach in IJ cannulation for HD catheter. It is, however, associated with a significantly high rate of interruption in HD blood flow and catheter insertion failure rates. The posterior approach can be used in patients with local exit site infection or in failed attempts to cannulate IJ vein via the conventional central approach.
Our study highlights the yet underestimated and neglected burden of ID in HF patients in India. This study suggests further large-scale studies to better characterize this easily treatable condition and considering routine testing in future Indian guidelines.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
