RESUMO
IMPORTANCE: Although cardiac injury is a known complication of COVID-19 infection, there is no established tool to predict cardiac involvement and in-hospital mortality in this patient population. OBJECTIVE: To assess if left ventricular global longitudinal strain (LV-GLS) can detect cardiac involvement and be used as a risk-stratifying parameter for hospitalised patients with COVID-19. MAIN OUTCOMES AND MEASURES: In-hospital mortality. RESULTS: We found a statistically significant association between LV-GLS and in-hospital mortality (adjusted OR (aOR)=1.09; 95% CI 1.0 to 1.19, p=0.050). Furthermore, right ventricular fractional area change was significantly associated with in-hospital mortality (aOR=1.04; 95% CI 1.0 to 1.08, p=0.043). Troponin level had no statistically significant association with in-hospital mortality (aOR=3.43; 95% CI 0.78 to 15.03, p=0.101). CONCLUSION AND RELEVANCE: LV-GLS can be a useful parameter for cardiovascular risk assessment in hospitalised patients with COVID-19 infection.

Heart failure is a leading cause of hospitalisations. Integration of palliative care services with medical therapy in the management of hospitalised patients with heart failure is imperative. Unfortunately, there are no standardised criteria for palliative care referrals among hospitalised patients with acute decompensated heart failure. The objective of our quality improvement project was to develop and implement a palliative care consult trigger tool for hospitalised patients with acute decompensated heart failure. We found that among eligible patients, palliative care referrals were underused, likely contributing to misalignment of goals of care and suboptimal advance care planning. We developed a trigger tool and designed and implemented structured multicomponent educational interventions to improve the appropriateness and timeliness of inpatient palliative care consultations in this high-risk population. The educational interventions led to a significant increase in the rate of appropriate inpatient palliative care consultations among hospitalised patients with acute decompensated heart failure (46.3% vs 27.7%; p=0.02). In addition, palliative care referrals resulted in better alignment of goals of care at the time of hospital discharge, as measured by a significant increase in the completion rate of a healthcare proxy form (11.4% vs 47.2%; p<0.001) and a Medical Order for Life-Sustaining Treatment form (2.0% vs 24.1%; p<0.001), as well as the establishment of a Do-Not-Resuscitate order (2.7% vs 29.6%; p<0.001). Furthermore, the intervention resulted in a significant decrease in the hospital readmission rate up to 90 days post-discharge (43.6% vs 8.3%; p<0.001). This quality improvement project calls for the development and adoption of standardised criteria for palliative care referrals to benefit hospitalised patients with heart failure and reduce symptom burden, align goals of care and improve quality of life.

BACKGROUND: Criteria for successful left bundle area pacing (LBAP) are in flux and currently guided by lead tip measurements. Lead ring measurements during LBAP have not been well studied. OBJECTIVE: The purpose of this study was to investigate dynamics in pacing parameters during successful and unsuccessful lead implant attempts. METHODS: SelectSecure 3830 pacing leads (Medtronic, Inc) guided by C315 sheaths for LBAP were placed for standard pacing indications in 73 patients. Retrospective review of procedural, echocardiographic, and standard pacing data were performed. Depth and lead-septal angle of implanted electrodes were determined from fluoroscopy with septal contrast delineation. Depth was graded in 4 categories according to the degree of ring penetration into the septum. Successful implant was defined by the ability to advance the lead deep into the septum and achieve LBAP criteria (ventricular activation time, QRS width/shape). RESULTS: Ring impedance increased stepwise during successful attempts as opposed to unsuccessful attempts (P = .039). A wider lead-septal angle at implant position correlated with higher ring impedance (P = .036), whereas no association was found with tip impedance. Unipolar ring threshold correlated with depth of lead implant (P = .029). Tip impedance measurements at implant position were less predictive of lead depth and did not correlate with septal thickness. CONCLUSION: Ring pacing parameters are more predictive of lead progress than tip measurements. Lead depth and lead-septal angle can be determined from ring impedance measurements. These measurements may provide determination of lead depth and could obviate the need for contrast injection.
