COVID-19 damages the heart in different ways, and more men may be at risk of death



Scientists have identified different types of structural injuries related to life-threatening cardiac deaths experienced by Covid-19 patients. These diseases are related to life-threatening blood clots and cardiac arrest. These findings may cause damage to people susceptible to these fatal diseases Perform better monitoring. According to a study published in the Journal of the American College of Cardiology, among hospitalized Covid-19 patients, these heart abnormalities are associated with a higher risk of death.

Researchers, including those from Mount Sinai Hospital in the United States, believe that the new insights can help doctors better understand the heart damage mechanism of people infected with the new coronavirus, so as to identify at-risk patients more quickly and provide future treatments guide.

The study’s co-author, Valentin Fuster of Mount Sinai Hospital, said: “Early detection of structural abnormalities may require more appropriate treatments, including anticoagulation and other methods for hospitalized and hospitalized patients.”

In the current study, the scientists studied the levels of troponin, which is released when the heart muscle is damaged, combined with abnormal cardiac scans observed with echocardiography.

The researchers found that the combination was associated with a worse prognosis and mortality compared with elevated troponin alone.

The study’s corresponding author, Gennaro Giustino from Mount Sinai Hospital, explained: “This is one of the first studies to provide hospitalized Covid-1

9 patients with detailed echocardiographic and ECG data and laboratory evidence of myocardial damage.”

Giustino said: “We found that among Covid-19 patients undergoing thoracic echocardiography, these cardiac structural abnormalities are diverse and exist in nearly two-thirds of patients.”

Scientists evaluated the heart scan results of 305 adult Covid-19-positive adult patients admitted between March 2020 and May 2020 in four New York City hospitals within the Mount Sinai Health System and two hospitals in Milan, Italy .

According to this study, the average age of the patients was 63 years old and 67.2% of men.

It noted that of the 305 patients, 190 had evidence of heart damage-118 of them had heart damage on admission and 72 had developed heart damage during hospitalization.

Scientists found that compared with patients without heart damage, patients with myocardial damage had more abnormal heart scans and higher levels of molecules indicative of inflammation.

They said that these abnormalities are different, and some patients show multiple signs of heart damage.

According to this study, 26.3% of patients had cardiac right ventricular dysfunction, and 23.7% of patients had local left ventricular wall motion abnormalities, which may be related to a heart attack.

Scientists say that 18.4% of people have heart abnormalities, which may be related to heart inflammation and heart damage, while 13.2% have grade II or grade III diastolic dysfunction-this condition causes the heart cavity to harden.

They said that 7.2% of the heart has too much water, which causes the heart to beat abnormally.

The researchers said they adjusted for other major complications of Covid-19, including shock, acute respiratory distress syndrome and renal failure.

According to scientists, the increase in troponin was 5.2% in patients without heart damage, while the increase in troponin was 18.6% in patients with myocardial damage but no abnormal cardiac scans, and 31.7% in patients with obvious heart damage. Use echocardiography.

“Our research has shown that echocardiography with appropriate personal protection factors is a useful and important tool for early identification of patients at higher risk of Covid-19-related heart damage, who may be hospitalized. Initially benefited from active treatments, said the co-author of the study, Martin Goldman of Icahn School of Medicine at Mount Sinai, USA.

Goldman said: “In addition, since this is a new disease with lingering symptoms, we plan to pay close attention to these patients through imaging to assess the progress of these heart problems and hopefully resolve them.
