Changing Trends of Mean Pulmonary Artery Pressure Reading During Covid-19 Pandemic Stay at Home Orders

Introduction Heart failure patients with difficult to manage volume status and recurrent heart failure exacerbation benefit from CardioMemsTM placement. This helps in remote monitoring of pulmonary artery (PA) pressure and diuretic dosing can be changed on the basis of these readings preventing hospitalizations. During the COVID-19 pandemic, a stay-at-home order was issued by the state government, which may have led to heart failure deterioration secondary to poor follow up and change in dietary habits. Hypothesis We aim to evaluate changes in the mean PA pressure during stay-at-home order during COVID-19 pandemic as patients are not seen in clinic and there are presumed changes in dietary habits. Methods We identified 26 patients with a history of CardioMemsTM implant using our heart failure clinic database. We extracted their daily available PA pressure reading before the COVID-19 pandemic and during pandemic. Results The characteristics of the patients are described in Table 1. 26 cases with were identified with sufficient CardioMemsTM readings. Average age was 69.7 years with 38.5% females. There were 54% patients with systolic heart failure. Number of COVID-19 cases rose to almost 700 in 1 month. With regression analysis, we observed a trend towards increase in the mean PA pressure readings during the pandemic (R2 = 0.09, P-value
