The Cardiac Implications of Novel Coronavirus
Recent clinical
bulletin addressing the cardiac implications of the novel coronavirus (COVID-19, 2019-nCoV and
Wuhan Coronavirus. The key message to clinicians is that patients with
underlying cardiovascular disease may have a potential increased risk if they
contract coronavirus
The bulletin provides
background on the epidemic, which was first reported in late December 2019, and
looks at early cardiac implications from case reports. It also provides
information on the potential cardiac implications from analog viral respiratory
pandemics and offers early clinical guidance given current 2019-nCoV
uncertainty. It stresses the importance for cardiovascular disease patients to remain
current with vaccinations, including the pneumococcal vaccine given the
increased risk of secondary bacterial infection and suggests encouraging the influenza
vaccination to prevent another source of fever which could be initially
confused with coronavirus infection.
The following points regarding early
cardiac implications from case reports on Wuhan Coronavirus.
• Early case reports suggest patients with underlying conditions are at
higher risk for complications or mortality from COVID-19; up to 50 percent of
hospitalized patients have a chronic medical illness.
• 40 percent of hospitalized patients with confirmed COVID-19 patients
have cardiovascular or cerebrovascular disease.
• In a recent case report on 138 hospitalized COVID-19 patients, 19.6
percent of patients developed acute respiratory distress syndrome.
• 16.7 percent of patients developed arrhythmia; 7.2 percent developed
acute cardiac injury.
• 8.7 percent of patients developed shock; 3.6% developed acute kidney
injury.
• Rates of complication were universally higher for ICU patients.
• The first reported death was a 61-year-old male, with a long history
of smoking, who succumbed to acute respiratory distress, heart failure and
cardiac arrest.
• Early, unpublished first-hand reports suggest at least some patients
develop myocarditis
