RESUMO
Background Around 80-85% of coronavirus disease 2019 (COVID-19) cases were reported to have mild disease and home treatment of such patients was proved to be effective without significant morbidity or mortality. Therefore, the aim of this study was to assess the outcome of home management of non-severe COVID-19 infection in healthcare providers in the developing world. Methods This observational cohort study was conducted at the National Institute of Cardiovascular Diseases from June 2020 till January 2021. It included health care workers who tested positive for COVID-19 with non-severe infection and received home treatment. The COVID-19 management team monitored their symptoms and oxygen saturation over the phone. Need-based lab tests, X-rays, home proning, steroids, and oxygen were administered along with the standard intuitional management strategies. Study outcomes included duration of recovery, need for hospitalization, and expiry. Results A total of 128 patients were included, out of which 98 (76.6%) were male, and the mean age was 32.9 ± 5.9 years. Fever was the most common symptom, seen in 89.8% of patients. Most of the patients (85.9%) had no pre-existing comorbidities. Five patients received home oxygen therapy, seven received steroid therapy, and one received home pruning. The average time of recovery was 13.8 ± 8.1 days with no mortality; however, 14 (10.9%) patients were hospitalized due to worsening of symptoms. Conclusion Home treatment for COVID-19 patients with mild to moderate disease after appropriate risk assessment can be a safe and effective option to preserve hospital capacities for more needy and severely ill patients.
RESUMO
Background ST elevation myocardial infarction (STEMI) is classically characterized by total occlusion of the culprit coronary artery. However during primary percutaneous coronary intervention (PCI) thrombolysis in myocardial infarction (TIMI) 0 flow is not observed in all patients' culprit arteries in angiographic views. This study was conducted to find out the frequency of TIMI flow in acute STEMI patients in view of the above concept. The aim of this study was to evaluate the frequency of pre-procedural TIMI III flow in those patients who underwent primary PCI for acute STEMI in a public sector hospital in Karachi, Pakistan. Methodology This study is an audit of already saved data in the catheterization laboratory of the National Institute of Cardiovascular Diseases (NICVD), Karachi, that was collected prospectively from January 2016 to December 2018. These data were collected after taking consent from those patients who presented to hospital within 12 hours of symptoms and underwent primary PCI. Data were entered and analyzed on Statistical Package for the Social Sciences (SPSS) version 19 (IBM Corp., Armonk, NY, USA). Results A total of 8018 patients were included in this study who presented with STEMI and underwent primary PCI. Out of them 80.9% were males. Hypertension was the leading risk factor in 54.1% (4340) of patients. TIMI III flow was present in 11.4% of patients before primary PCI, while TIMI 0, I and II flow were present in 57.1%, 15.1%, and 16.3% of patients respectively (p<0.001). Fourteen percent of patients with TIMI III flow were of age group 51 to 60 years. Among those who had TIMI III flow, 11.2% were those with door to balloon time of <90 minutes. In 11% of cases, left anterior descending (LAD) artery had TIMI III flow as compared to other vessels (p<0.001). The length of the lesion was significantly smaller in patients who had TIMI III flow compared to those who had TIMI 0-II flow. Conclusions This study revealed that not all patients with acute STEMI had totally occluded culprit coronary artery but some of them had angiographic TIMI I-III flow in the infarct-related artery. Further studies are needed to find the reason for re-establishment of flow in the culprit vessel in STEMI patients before PCI.
