Coronavirus patients with heart disease have a 10% chance of dying. Here's the mortality rate for patients with various underlying health problems.
Coronavirus patients with underlying health problems are more likely to die from the virus, a recent Chinese CDC study found. The study found that patients with heart disease had a 10% chance of dying. In general, older patients are the most likely to suffer severe symptoms and die. The first patient to die of the coronavirus in the US was a man in his 50s who had been chronically ill. Visit Business Insider's homepage for more stories.
Older patients and people with preexisting health conditions face the highest risk of dying from the new coronavirus, a recent study found. The study, done by the Chinese Center for Disease Control and Prevention, found that the overall chances of dying from COVID-19 — the disease caused by the virus — are 2.3%. Other estimates suggest the fatality rate could be higher: around 4.3%. The current rate, based on the ratio of reported deaths to total cases worldwide, hovers around 3.4%. But the Chinese CDC study found that the fatality rate rate rose to 8% for patients in their 70s and 15% among those in their 80s.Out of more than 44,000 coronavirus patients studied, the majority of deaths were among those at least 60 or older. Older patients are also more likely to have preexisting health problems. The first patient to die of the coronavirus in the US, for instance, was a man in his 50s who had been chronically ill before getting infected. Nearly 5,300 patients in the Chinese study reported a health condition not related to the virus, such as cancer, heart disease, or diabetes. Around 7% of those cases — more than 370 patients — died. Overall, patients with preexisting conditions represented more than a third of all deaths reported in the study. The fatality rate for patients who reported no underlying health problem was less than 1%. Here's the mortality rate for each preexisting condition reported in the study:
The authors were missing the health history of more than 20,000 patients in their study, but their research is still provides one of the broadest pictures so far of how COVID-19 operates in humans. Among coronavirus patients, the preexisting condition that raises risk most appears to be heart disease. Patients already diagnosed with heart disease had a fatality rate of more than 10%. Diabetes was the preexisting condition with the second-highest fatality rate: 7%. Patients with the most commonly reported preexisting condition, hypertension (high blood pressure), had a fatality rate of 6%. Coronavirus patients with cancer had a similar fatality rate. In total, COVID-19 has killed nearly 3,000 people and infected around 86,000. The outbreak originated in Wuhan, central China's most populous city, and has since spread to at least 58 other countries. More than 90% of cases are on the Chinese mainland. Read more:

Unlike the rest of the world, Canada is seeing more COVID-19 deaths in women than in men. Here's why.
While the rest of the world is witnessing more men dying of COVID-19 than women, Canada...While the rest of the world is witnessing more men dying of COVID-19 than women, Canada is one of the only countries where that statistic has been reversed. The Canadian province of Quebec is seeing the biggest gender disparity in coronavirus cases, with women making up 59.4% of confirmed coronavirus cases and 54.6% of deaths. Experts believe that the data could be skewed towards females because the province has seen the majority of its outbreak occur in long-term care homes, where the population of females is a lot higher. Another factor is that healthcare workers in the province — of which 80% are female — have also been largely affected. Visit Business Insider's homepage for more stories. Early research into the novel coronavirus has shown an unusual pattern among COVID-19 patients: more men are dying than women. But Canada seems to be bucking the global trend, with the latest data showing that it is one of the few countries where women have higher death and infection rates than men. The virus has been particularly devastating for the eastern province of Quebec, which, to date, has more than 42,000 confirmed coronavirus cases and almost 3,500 deaths alone— the highest in the country, according to government statistics. Quebec also sees the greatest gender disparity in COVID-19 cases out of all the provinces. As of May 14, women made up 59.4% of confirmed coronavirus cases and 54.6% of deaths, the Montreal Gazette reported. But why? While research is still underway and the lack of community sampling doesn't show the full picture, some experts believe that there are several explanations as to why the province — and Canada as a whole — is seeing a gender difference of infection and death rates, compared with the rest of the world. Quebec has seen one of the worst outbreaks in its long-term care facilities A large part of Quebec's battle against the coronavirus has been fought in its long-term care facilities, Dr Donald Sheppard, a professor and Chair of the Department of Microbiology and Immunology (MI4) at McGill University, told Business Insider. "One factor is that the outbreak in Quebec is a very different outbreak than what has been seen in other provinces. It's being driven not by community spread, but by a spread in long-term care facilities," Sheppard said. The virus was first brought into care homes by family members who had taken trips abroad during the province's early March break. A failure by authorities to respond quickly and effectively in the days and weeks that followed caused COVID-19 to spread rampantly in dozens of homes, according to the Canadian Broadcasting Corporation (CBC). The situation was worsened by massive staff-shortages of personal protective equipment (PPE) as thousands of care home workers started getting infected with the virus. According to provincial data, 82% of Quebec's dead lived in long-term care homes. On top of that, women make up over 75% of residents aged 85 years and older in care homes, according to data cited in the Montreal Gazette. "What we're seeing here is that a lot of the numbers are being skewed by the fact that we assume that we're taking 50/50 men and women, exposing them to the virus, and what's coming out of the other end is the numbers that you're getting now," Sheppard said. "I actually think what we're doing is taking a population that is around 75% female, exposing them to the virus, and that female portion of that population is older than the male fraction so they're more at risk for bad outcomes and shockingly, this is what you're seeing." "And to make matters worse, the average age of the women in the long-term care facility is older than the average age of the male. And we know there is a direct correlation between age and severity of this illness and its mortality," Sheppard added. Philip Goulder, a pediatrician and research immunologist at the University of Oxford, agrees with Sheppard that when you look only at the population of older people in the country opposed to the total population, the numbers change. "People haven't taken into account when they look at the male and female statistics, the fact that it shouldn't be just 50/50. It should be 60/40, for example, because women live older than men," Goulder told Business Insider "Even in Canada, the number of males dying is still far more than you expect because you got fewer men who are over 70 than females," he added. The problem of outbreaks in long-term care facilities has been witnessed in other parts of Canada too. In April, Canada's chief public health officer Theresa Tam said that nearly half of the known coronavirus deaths in the country were linked to outbreaks in elderly care homes, according to the BBC. Healthcare workers in the province have also been affected badly Another explanation for the different gender disparity in Canada could be that the virus has affected frontline healthcare workers in the country. Women form 70% of workers in the health and social sector worldwide, according to a report by the World Health Organisation (WHO) In Quebec, this number is much higher, with an estimated to be 80% of the workforce comprised of women, according to the Fédération de la santé et des services sociaux (FSSS-CSN) — the largest union representing the province's healthcare workers. "So the healthcare worker population is estimated to be 80% women already, and if you think about what it is in long-term care, it's skewed even further —it's probably closer to 90% of healthcare workers in this setting are female," Sheppard said. According to the CBC, at least 4,000 healthcare workers have tested positive for COVID-19 in Quebec, making up the second-largest portion of infections outside nursing homes. "It's such a massive part of the outbreak. If you think about the fact that 20% of all the cases in the province are healthcare workers," said Sheppard. "We're seeing the dramatic difference between the community outbreak which is smaller, and then the hospital associate outbreak with healthcare workers and with patients in the outbreak," he added. Sheppard believes that is could be the combination of the virus breaking out in long-term care facilities and affecting predominantly healthcare workers in the province that are skewing the numbers that show more women are dying. "If we can split off just the community data in Quebec, people that are not healthcare workers and are not long-term care facility patients, I really think we would see that the balance would be the same as what we have seen in other countries," Dr Speppard said. "In the community, we might have a 50/50 mix, but in long-term care facilities and healthcare workers it's absolutely skewed towards females," he added. Most countries in the world are witnessing a different trend Meanwhile, researchers in other countries have been trying to understand why men seem to be dying at a higher rate than women. One of the first studies that looked into the gender differences in COVID-19 cases was conducted by the Chinese Center for Disease Control and Prevention at the beginning of the year. The study found that out of more than 44,000 patients, 2.8% of men diagnosed with the coronavirus ultimately died as of February 11. For women, the fatality was 1.7%. Researchers quickly realized that the trend wasn't exclusive to China and that countries, including Italy, Germany, and South Korea, also started reporting a higher death toll among male patients, according to academic research group Global Health 50/50. Several possible explanations behind this trend have since been discussed. One factor could be that men smoke cigarettes more than women do. Other researchers have pointed to behavioral factors as another possible explanation — surveys suggest US men are less likely to wash their hands. Another possibility could be that those with preexisting health conditions like high blood pressure or heart disease are more likely to die from the virus. In many countries, men usually have higher rates of these underlying health issues.

The coronavirus can damage the heart, even in people with no history of heart disease, new research suggests — showing it doesn't only affect the lungs
People with underlying health conditions are disproportionately at risk of severe complications from the coronavirus. The...People with underlying health conditions are disproportionately at risk of severe complications from the coronavirus. The death rate for coronavirus patients with heart disease is around 10%, some research suggests. That's because the virus can cause damage to the heart and surrounding tissues, and that damage can lead to death. New research suggests the coronavirus can even injure healthy coronavirus patients' heart muscles or cause partial heart failure, including among people who do not present respiratory symptoms. Visit Business Insider's homepage for more stories. While the most severe cases of the new coronavirus typically involve respiratory failure, COVID-19 doesn't always solely impact a patient's lungs. The virus sometimes causes infection and swelling in the heart and surrounding muscles, which can be fatal. New research published Friday in the journal JAMA Cardiology concluded that the COVID-19 virus, much like other respiratory viruses, can impact a patient's cardiac system. The study found that even healthy people who contract COVID-19 are at risk of heart injury. "It is likely that even in the absence of previous heart disease, the heart muscle can be affected by coronavirus disease," Dr. Mohammad Madjid, the study's lead author and an assistant professor of cardiology at McGovern Medical School at UTHealth, said in a press release. "Overall, injury to heart muscle can happen in any patient with or without heart disease, but the risk is higher in those who already have heart disease," he added. The link between COVID-19 and cardiac problems After reviewing an array of existing studies about COVID-19, Madjid and his colleagues affirmed that patients with preexisting heart disease are among those at the greatest risk for developing severe cases of COVID-19. The scientists concluded that those patients' risks are two-fold: not only do they seem more likely to get infected due to their underlying heart disease, but they are also more likely die from the illness, in part because they develop further heart injuries during infection. The case fatality, or death rate, for COVID-19 patients with heart disease in mainland China was 10.5% between December 30 and February 11, according to research from the Chinese Center for Disease Control and Prevention. According to another new study in JAMA Cardiology (which echoed Madjid's group's conclusions), that's because patients with underlying heart disease are more prone to experience myocardial, or heart, injury during the course of their COVID-19 infections. These myocardial injuries include an irregular heartbeat or heart failure. The study, which examined 187 COVID-19 patients at a hospital in Wuhan, China, revealed that 28% of patients developed a myocardial injury, which was significantly associated with a higher risk of death. About 70% of patients that had both underlying heart disease and developed a heart injury from the virus died. According to Madjid and his co-authors, COVID-19, as well as other respiratory viruses like the flu and SARS, can exacerbate existing cardiovascular disease and trigger new heart problems in healthy patients. During most flu epidemics, more patients die of heart problems than respiratory issues like pneumonia, they wrote, adding that they expect similar cardiac issues among severe COVID-19 cases. One woman with COVID-19 had a heart infection but no respiratory issues A third study also published Friday in JAMA Cardiology describes the case of a 53-year-old healthy woman without any history of cardiovascular disease or underlying health conditions. She came to the emergency room complaining of severe fatigue in March. The patient told doctors that she'd had a fever and dry cough the week before, but she had no difficulty breathing and her chest x-rays were clear. The lining of her heart, however, was inflamed and infected, and she was admitted to the cardiac care unit for treatment. Later, because of her prior symptoms, she was given a coronavirus test. It came back positive. The study authors wrote that this woman's case "provides evidence of cardiac involvement as a possible late phenomenon of the viral respiratory infection." The researchers offered two possible explanations about how the COVID-19 virus might impact the heart. The first is that the virus could spread from the lungs through the body via blood or the lympathic system. They added, however, that no incidences of the coronavirus in the heart had been reported yet. Alternatively, the coronavirus could trigger inflammation in the body, which may cause heart injury.Join the conversation about this story » NOW WATCH: Pathologists debunk 13 myths about the coronavirus, including why masks won't help
