BACKGROUND AND OBJECTIVE.

Severe Acute Respiratory Syndrome - Coronavirus-2 (SARS-CoV-2) was initially known to affect the respiratory system and has been reported to also involve the cardiovascular system leading to myocardial damage. Remdesivir is one of the approved treatments for COVID-19, wherein viral replication is inhibited by terminating the RNA transcription prematurely. According to studies, the primary electrocardiographic effect of remdesivir in COVID-19 patients are sinus bradycardia and QT prolongation. The use of electrocardiogram (ECG) is an essential diagnostic tool in assessing the electrical conditions of the heart. The objective of this study is to describe the electrocardiographic profile of adult patients with COVID-19 who were given remdesivir and admitted in the University of the Philippines-Philippine General Hospital (UP-PGH). To this date, this is the only study done locally identifying the electrocardiographic profiles of adult patients with COVID-19 who were given remdesivir.

METHODS

This was a retrospective descriptive study involving adult patients with COVID-19 who were given remdesivir and admitted in UP-PGH from June 2021 to June 2022. Demographic profiles and 12-lead ECG done during the hospital admission were gathered. Descriptive statistics was used to summarize the clinical characteristics and the electrocardiographic findings of the patients.

RESULTS

There were 412 confirmed COVID-19 patients who were given remdesivir (mean age 56 years old; female 52%) included in this study. The most common comorbidities were hypertension, diabetes mellitus, and stroke. Majority of the patients had severe (58%) to critical (22%) COVID-19 infection. Most of the patients had sinus rhythm (94%), normal rate (72%), and normal axis (93%). The most common baseline ECG findings were non-specific ST-T wave changes (42%). Some patients had atrioventricular blocks (3.4%), bundle branch blocks (3.6%), prolonged QT interval (1.9%). Among those with repeat 12-L ECG (136 patients) during admission, ECG changes observed were sinus bradycardia (6%), prolonged QT interval (4%), and both (1.5%).

CONCLUSION

Based on this retrospective review, which to our knowledge is the only study done locally investigating the effects of remdesivir on ECG of adult Filipino patients with COVID-19 infection, majority of the patients had sinus rhythm, normal rate, and axis. The most common ECG finding was non-specific ST-T wave changes. This study demonstrated a low incidence of adverse ECG changes that would preclude the administration of remdesivir when indicated. These include sinus bradycardia and QT interval prolongation which did not require further interventions. ECG remains to be useful, low-cost noninvasive tool that can help monitor electrophysiologic adverse events of remdesivir.

BACKGROUND AND OBJECTIVE

Physician adherence to the recommended management of patients with heart failure with reduced ejection fraction (HFrEF) at the outpatient setting is crucial to reduce the burden of subsequent rehospitalization, morbidity, and mortality. Recently updated guidelines recommend early and rapid titration to optimal doses of medications in the first 2 to 6 weeks of discharge. In the absence of local data, our study evaluates physician adherence to guideline-recommended treatment in this setting.

METHODS

This is a retrospective cross-sectional study among post-discharge HFrEF patients at the outpatient department from December 2022 to May 2023 with a follow-up within three months. Clinical profile and treatment were extracted from medical records. Adherence to the 2021 ESC Guidelines Class I recommendations, among eligible patients, is measured as quality indicators. Data are presented using descriptive statistics.

RESULTS

A total of 99 patients were included in the study. Overall, adherence to prescription of beta-blockers (94.8%), ACEI/ARNI/ARBs (88.5%), and diuretics (100%) were high. Prescription of mineralocorticoid receptor antagonists (MRA) and sodium-glucose cotransporter-2 inhibitors (SGLT2i) were 67% and 57.3%, respectively. Over three months of follow-up, improvement in the quality of care was demonstrated with ACEI/ARNI/ARBs (81.8% to 90.9%), MRA (68.7 to 81.2%), and SGLT2i (58% to 67.7%). Beta-blocker use is consistently high at 97%. In the 3rd month post-discharge, titration to optimal doses was achieved in only 26.4%, 15%, and 6.25% for those on beta-blockers, ACEI/ARNI/ARB, and MRA, respectively. For non-pharmacologic management, referral to HF specialty was made in 30% and cardiac rehabilitation in 22.2%.

CONCLUSION

Among patients with HFrEF seen at the outpatient, there is good physician adherence to betablockers, ACEI/ARNI/ARBs, and diuretics. MRA and SGLT2i prescription, referral to HF specialty and cardiac rehabilitation, and up-titration to optimal doses of oral medications for HF need improvement. Hospital pathway development and regular performance evaluation will improve initiation, maintenance, and up-titration of appropriate treatment.

INTRODUCTION

Sinus of Valsalva aneurysms (SOVA) are rare conditions in which a portion of the aortic root dilates due to weakness of the aortic wall, which can eventually lead to rupture, leading to a shunt from the aorta into any one of the cardiac chambers. Some patients can present asymptomatically and are diagnosed incidentally, while others can present with precipitous courses with symptoms of chest pain, palpitations and heart failure. When left untreated, these patients have poor prognosis.

CASE DESCRIPTION

A total of six patients are presented in this case series. These patients were seen in a national tertiary hospital from 2018 to 2024. The patients had varied characteristics, with ages ranging from 24-57 years old. Most of the patients were males. The presenting symptoms are also varied, with dyspnea being the most common symptom and a murmur being the most common sign. The most commonly involved sinus was the right coronary sinus draining into the right ventricle, with half of the patients presenting with concomitant ventricular septal defects. Five out of the six patients underwent successful open repair of their ruptured SOVAs and were eventually discharged.

DISCUSSION

Early identification of the cardiac lesion is important to clinch the diagnosis and plan for eventual definitive management. Imaging studies such as transthoracic echocardiogram are needed to visualize the defect, which is classically described as a windsock deformity. Transesophageal echocardiography may present clearer images to assess the anatomy better preoperatively. Medical management is usually done to bridge the patient to more definitive therapy, either through endovascular closure if the anatomy permits it or through surgical repair. Urgent and timely repair is needed to ensure improved survival in these patients.
