Abstract
Background Previous studies have identified that adults with cardiovascular diseases were disproportionately associated with a significantly increased risk of a severe form of COVID-19 and all-cause mortality. We aimed to describe the diagnosed COVID-19 cases and to estimate the symptomatic and asymptomatic suspected cases among individuals with pre-existing myocardial infarction myocardial infarction and their relatives in lockdown period. Methods: We conducted a two-week cross-sectional telephone survey, from May 4 to May 15, 2020, including all households with at least one individual with pre-existing cardiovascular disease in the past two years. We defined a suspected COVID-19 case when living with at least one individual tested positive to COVID-19, or when an individual has been in contact with a suspected or confirmed case since the March 1rst, or when a relative from the same house has been hospitalized or deceased for COVID-19.
Results We observed high rates of compliance with health measures during the lockdown period, regardless of age or risk factors. Among individuals with myocardial infarction history, two were COVID-19 confirmed, 13·37% were suspected (94/703) of whom 70·21% (66/94) asymptomatic.
Conclusions Individuals with myocardial infarction history presented different symptoms association with more respiratory signs. This population, which is older and associated with more comorbidities, is exposed to a high risk of complication in the event of contamination. Infection rates are relevant to adjusting the management of emergency departments in our region.
