Cardiac Arrest and Covid-19

Recommended Posts

"Coronaviruses are a large family of single positive-stranded, enveloped RNA viruses that can infect many animal species and humans. Human coronaviruses can be divided based on their pathogenicity. The types with high pathogenicity including SARS-CoV, MERS-CoV, and the current novel SARS-CoV2.[1] Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has led to possibly the worst pandemic of this century in the form of Coronavirus disease 2019 (COVID-19). Initially recognized as a respiratory system disease, COVID-19 has been found to interact with and affect the cardiovascular system leading to myocardial damage and cardiac and endothelial dysfunction mainly via the Angiotensin-converting enzyme 2 (ACE-2) receptor.

The involvement of cardiac factors was recognized early in the pandemic in reports from China. A retrospective analysis of 187 patients treated in a Wuhan hospital between January 23 and February 23, 2020, found that 35% had existing cardiovascular comorbidities such as hypertension, coronary disease, and cardiomyopathy, and 28% exhibited myocardial injury indicated by elevated troponin T levels [9]. Other Chinese reports found rates of baseline cardiovascular disease ranging from 5% to 16%, hypertension ranging from 15% to 31%, coronary artery disease of 11%, and diabetes of 10%.

Beyond China, even higher rates of these comorbidities have been reported. A retrospective case series from Italy presented results from 1,591 critically ill patients with COVID-19 who were admitted to the intensive care unit (ICU): 49% of patients had hypertension, 21% had cardiovascular disease, and 17% had diabetes.[11] In a study from New York between March 2 and April 1, 2020, 1150 adults with COVID-19 were admitted to two hospitals; 257 were critically ill. Of these, 82% had at least one chronic illness, the most common of which were hypertension (63%), diabetes (36%), obesity (46%), and heart disease (19%).[12] In a large case series of 5700 patients with COVID-19 admitted to 12 hospitals in New York, the prevalence of hypertension, diabetes, and coronary artery disease was 57%, 34%, and 11%, respectively." 

It would really makes sense if people with underlying conditions like heart disease to be extra careful and to just stay at home as much as possible away from people with high risk of getting infected with Covid-19 like frontliner. Even with vaccine, it's not a guarantee of significant decrease in getting worse condition if contracted with the virus. If you have or have a family with these conditions, how are you dealing with this? Any thoughts?

My family has always been careful especially this pandemic. We make sure our parents are protected because seniors have high risk of getting infected and they both have underlying conditions.
