The alarming symptoms of COVID-19 have led scientists to uncover potential long-term heart damage in COVID-19 patients. As happened to Melissa Vanier, 52, the first time she fell ill with coronavirus in late February after returning from a trip to Cuba in the Caribbean.
In May, he was already free from Covid-19, but noticed that his heartbeat seemed abnormal and immediately sought medical advice. At that time, he didn’t know much about the long-term effects of the Corona virus, but a cardiologist tested Melissa and measured the blood flow to her heart.
“This shows that he has ischemic heart disease, which means his heart is not getting enough blood and oxygen,” said Dr Melissa.
Like Melissa, Nicola Allan, 45, of Liverpool, also experienced a higher than usual heart rate two months after contracting the Corona virus COVID-19.
“It could be in the middle of the night or during the day. I was starting to shake and had to hang on to the wall for support. But cardiologists still don’t understand why this happened,” Allan said.
City of The GuardianBoth stories reflect a broader trend that patients can experience lasting heart damage after the first symptoms of COVID-19 go away. Peter Liu, chief of science at the University of Ottawa Heart Institute, participated in the analysis of clinical data to understand the impact of COVID-19 on the heart.
Liu said his team found the coronavirus to have a “ surprising ” impact on heart health, which is more common in patients with COVID-19 than SARS.
“The SARS virus has caused heart damage in a small proportion of patients. However, the rate of heart damage from COVID-19, as evidenced by the release of biomarkers such as troponin in hospitalized patients, is quite surprising.” , Liu said.
In a study, analyzed by Liu, a cardiologist at Wuhan University’s Renmin Hospital found that out of 416 patients, nearly 20% had heart injuries. Liu says although a third of coronavirus patients show signs of heart damage in blood tests, many will recover.
Cardiac electrophysiologist Raul Mitrani, from the University of Miami, said the amount of scar tissue remaining in a patient after treatment plays an important role in determining a patient’s long-term prognosis.
“If there is inflammation, resulting in heart dysfunction, there is a reasonable chance of recovery. If the heart cells die and are replaced by scar tissue, then the problem lies according to the percentage of the heart affected,” he said. Mitrani explained.
“If we look at the scar tissue, and especially if there is enough of it to impair heart function, we will be concerned about the potential for heart failure and arrhythmias in the future,” he concluded.
