Lessons learnt from COVID-19 in adult congenital heart patient in Tehran: a survey-based study of prevention, exposure, susceptibility, and outcomes.

BACKGROUND: COVD-19 pandemic has overwhelmed many healthcare systems worldwide. Underlying cardiovascular disease predisposes to greater disease susceptibility and more complications including mortality. Such data is unverified in adults with congenital heart disease (ACHD). The aim of the study is to report the Tehran experience with respect to preventative self-care measures, disease exposure, susceptibility, and outcomes after COVD-19 infection in ACHD patients. METHODS: A telephone-based survey was conducted in ACHD patients, focusing on new-onset symptoms that might indicate COVID-19 infection, prevention measures, confirmed infection rates, and outcomes. RESULTS: Three-hundred and nine ACHD patients, with a mean age of 29.13 years (range from 14 to 72 years, SD = 10.64), and 170 (55%) women were assessed. The majority (86.7%) had moderate or complex ACHD. Two-thirds (67.3%) of the patients practiced high-level preventative self-care measures. After community exposure, 33.3% developed COVID-19, and after household exposure, 43.7% developed COVID-19. There was only one mortality in a post-operative patient. Thirty-seven patients (12%) reported new symptoms including cough (10%), fatigue (8%), fever (7%), and new dyspnoea (6.5%). Amongst 18 (6%) with confirmed COVID-19, there was only 1 mortality in a post-operative patient. Age (adjusted OR = 1.19, 95% CI: 1.07-1.31, p = 0.001), contact with confirmed COVID-19 cases (adjusted OR = 59.34, 95% CI: 3.68-955.10, p = 0.004) were independently associated with COVID-19 infection. CONCLUSIONS: Mortality risk associated with COVID-19 infection in ACHD patients with moderate or severe disease appears to be relatively low, similar to the general population. Such risk appears to act through conventional risk factors, and in this cohort, we demonstrated age as a significant risk factor in addition to exposure to the development of COVID-19 infection. Preventative self-care measures are a potentially significant and impactful intervention target for intervention and for improving outcomes.

Management principles in patients with COVID-19: perspectives from a growing global experience with emphasis on cardiovascular surveillance.

The COVID-19, due to SARS-CoV-2, has uncovered many real-world issues when it comes to healthcare management and has led to a widespread mortality. Observations thus far from the reports of COVID-19 have indicated that certain risk groups for example, those with pre-existing cardiovascular (CV) disease, hypertension, diabetes, chronic kidney disease and tobacco use are prone to disease development and specifically development of severe disease and possible fatality. It is increasingly evident that many CV conditions occur frequently. These include myopericarditis, acute coronary syndromes, thrombosis, arrhythmias, hypertension and heart failure. Many professional organisations and societies related to cardiology have produced guidelines or recommendations on most of the above-mentioned aspects. Given these rapid developments, the aims of this review manuscript were to summarise and integrate recent publications with newly developed guidelines and with the first-hand experience of frontline physicians and to yield a pragmatic insight and approach to CV complications of COVID-19. We emphasise on a strategic tier-based approach for initial assessment and management of COVID-19, and then delve into focused areas within CV domains, and additionally highlighting the role of point-of-care ultrasound especially lung ultrasound, echocardiography and electrocardiography, in the management of these patients. We hope this paper will serve as a useful tool in the CV management of COVID-19 for clinicians practicing in both developing and developed countries.
