Our fucking failures of stroke associations should be publishing similar research on stroke since we had massive amounts of inflammation in our brains. BUT NOTHING WILL OCCUR! You're screwed. You will have to do your own research on that issue. You are responsible since no one in stroke is up to the task of solving stroke and associated consequences.
Cardiac injury confers greater mortality in patients with COVID-19
Among patients with
laboratory-confirmed COVID-19 in Wuhan, China, those with cardiac injury
had a higher risk for in-hospital mortality than patients without
cardiac injury.
According to new research published in JAMA Cardiology, cardiac injury, defined as blood levels of high-sensitivity troponin I above the 99th percentile upper reference limit, appears common among patients hospitalized with COVID-19. Researchers reported cardiac injury occurred in 19.7% of a cohort of 416 consecutive patients.
In-hospital mortality occurred in 51.2% of patients with cardiac injury vs. 4.5% of those without cardiac injury (P < .001), according to the researchers.
Risk for in-hospital death was elevated in patients with cardiac injury and COVID-19, compared with patients with COVID-19 but no cardiac injury, regardless of whether the starting time point was symptom onset (HR = 4.26; 95% CI, 1.92-9.49) or hospital admission (HR = 3.41; 95% CI, 1.62-7.16).
Complication rates
Moreover, patients with cardiac injury experienced higher rates of complications than those without cardiac injury, including acute respiratory distress syndrome (58.5% vs. 14.7%; P < .001), acute kidney injury (8.5% vs. 0.3%; P < .001), electrolyte disturbances (15.9% vs. 5.1%; P = .003), hypoproteinemia (13.4% vs. 4.8%; P = .01) and coagulation disorders (7.3% vs. 1.8%; P = .02).
Researchers also observed that among those with COVID-19, those with cardiac injury more often required noninvasive mechanical ventilation (46.3% vs. 3.9%; P < .001) or invasive mechanical ventilation (22% vs. 4.2%; P < .001) compared with those with no cardiac injury.
“The present study demonstrates the statistically significant association between cardiac injury and mortality in patients with COVID-19,” Shaobo Shi, MD, PhD, of the department of cardiology at Renmin Hospital and the Cardiovascular Research Institute at Wuhan University, China, and colleagues wrote. “Cardiac injury ... was associated with an unexpected high risk of mortality during hospitalization.”
Patient characteristics
Researchers also observed that among patients diagnosed with COVID-19, those with cardiac injury, compared with those without, were more likely to have (P < .001 for all except as noted):
“The present study lacks evidence from magnetic resonance imaging or echocardiography to determine the features of myocardial injury,” the researchers wrote. “On the basis of the present results of high-sensitivity troponin I and ECG findings in a subset of patients, we can only estimate the severity of cardiac injury. Thus, because of the current limited evidence, the question of whether the SARS-CoV-2 virus can directly injure the heart requires further demonstration.” – by Scott Buzby
