Scientist said; Patients who are admitted to an intensive care unit (ICU) may be ten times more likely than others hospitalized with the viral infection to suffer cardiac arrest or heart rhythm disorders, according to a new study which may help better protect those most vulnerable to the disease. Researchers, including those from the University of Pennsylvania in the US, said cardiac arrests and heartbeat rhythm disturbances suffered by some patients with the disease are likely triggered by a severe, systemic form of the disease, and are and not the sole consequence of the viral infection. The findings, published in the Heart Rhythm Journal, differ significantly from early reports which showed a high incidence of arrhythmias among all COVID-19 patients, according to the scientists.
They said the results provide more clarity about the role of the novel coronavirus, SARS-COV-2, and the disease it causes, COVID-19, in the development of arrhythmias, including irregular heart rate, slow heart rhythms, or rapid heart rate that stops by itself within 30 seconds.
“In order to best protect and treat patients who develop COVID-19, it’s critical for us to improve our understanding of how the disease affects various organs and pathways within our body — including our heart rhythm abnormalities,” said study senior author Rajat Deo from the University of Pennsylvania. “Our findings suggest that non-cardiac causes such as systemic infection, inflammation, and illness are likely to contribute more to the occurrence of cardiac arrest and arrhythmias than damaged or infected heart cells due to the viral infection,” Deo said.
Earlier studies had suggested that COVID-19 is associated with a high incidence of cardiac arrhythmias, particularly among critically ill patients with early reports indicating that 44 per cent of patients admitted to the ICU suffered heartbeat rhythm disturbances. According to the researchers, heart rhythm problems occur when electrical impulses that coordinate heartbeats don’t work properly, causing the heart to beat too fast, too slow, or irregularly. If left untreated, they said cardiac arrhythmias can lead to serious medical conditions, including stroke and cardiac arrest — the abrupt loss of heart function.
Good findings
There is always new discoveries concerning this disease. The other time there was the discovery that children in the US developed blisters on their feet after recovering,now this.
