# Signs and symptoms of covid − 19 in patients with a history of coronary artery bypass grafting surgery

## TL;DR

This study explores how people who had heart surgery respond to COVID-19 symptoms and finds that loss of taste and smell are significant indicators.

## Contribution

The study identifies specific symptoms and behaviors linked to COVID-19 in CABG patients, offering insights into their vulnerability.

## Key findings

- Loss of taste and smell are strongly associated with COVID-19 symptoms in CABG patients.
- Non-compliance with home quarantine increases the likelihood of showing symptoms.
- CABG patients do not show higher symptom frequency than healthy individuals in the Iranian population.

## Abstract

People who have coronary artery disease are more likely to develop signs and symptoms of COVID-19 due to their special circumstances. Coronary artery bypass grafting surgery (CABG)does not cure the disease but reduces the signs and symptoms, therefore, there is a possibility of severe complications of Covid-19 after it.

This study is a descriptive and cross-sectional study conducted from June to July 2020 on 200 patients who underwent CABG from February 2018 to February 2020. The instrument consisted of socio-demographic variables and COVID’s signs and symptoms checklist. Data were collected by census method by telephone. Data were analyzed using descriptive statistics, Fisher’s exact test, Mann Whitney U test, and logistic regression model.

The results showed that the majority of the samples were male (67%). The mean age of them was 62.02 ± 9.06 years and 10% of the m had signs and symptoms of Covid 19. Having the symptoms of COVID-19 is significant in terms of the variables of decreased sense of smell (p < 0.002), decreased sense of taste (p < 0.002), and home quarantine (p < 0.01). The logistic regression model showed decreased sense of taste (OR = 6.071, CI95%: 1.621–29.984, p < 0.009) and non-compliance with home quarantine (OR = 0.061, CI95%: 0.005–0.741, p < 0.028) were the related variables to signs and symptoms of Covid 19.

The results did not indicate the frequency of COVID signs and symptoms among people with a history of Coronary artery bypass grafting surgery more than healthy people in the Iranian community. Extensive studies are suggested in this regard.
