Births between June and August are more susceptible to cardiovascular disease

. scientists screened cardiovascular data from 129,778 dogs and found that dogs born between June and August were more likely to develop cardiovascular disease than dogs born in other months, according to a biological study published Tuesday. The dog's heart is considered an effective model of human heart physiology because the two have very similar cardiovascular systems.
Cardiovascular disease is a common term for cardiovascular and cerebrovascular diseases, which generally refers to isoemia or haemorrhagic diseases in the heart, brain and systemic tissues caused by hyperlipidemia, blood viscosity, atherosclerosis, hypertension, etc., and the resulting deaths are currently the highest of all causes of death. This time, Researcher Marley Regener Boland of the University of Pennsylvania and colleagues looked at dogs to see if the month they were born affected their risk of cardiovascular disease.
they analyzed cardiovascular data from 129,778 dogs in 253 different breeds and found that dogs born between June and August had a higher risk of cardiovascular disease than dogs born between June and August in breeds that did not have genetic susceptible to cardiovascular disease. However, the birth season does not seem to affect dogs that are already genetically susceptible to cardiovascular disease.
team stressed that since the relationship between the birth season and cardiovascular disease is more pronounced in dogs that are not genetically susceptible, the effect is likely due to environmental factors. One factor may be selective breeding, in which dogs prone to cardiovascular disease are more closely "monitored" than dogs that are less prone to disease. The researchers believe there may also be genetic factors that make dogs less susceptible to cardiovascular disease more vulnerable to adverse environmental effects associated with the birth season.
dogs and humans have similar cardiovascular systems and are exposed to similar environmental pressures because they live with humans. As a result, the researchers believe the latest findings are likely to help understand the relationship between cardiovascular disease in humans and its birth season.
