United States: Although such side effects are really very rare to see as the new studies reveal that they occur more than balance out by heart-health improvement after a COVID-19 vaccine shot.
It showed that individuals who received their COVID and boosters are about 90 percent less likely to suffer from major issues linked to heart complications arising from the virus infection.
As reported by HealthDay, adverse cardiovascular effects witnessed after COVID vaccination are short-term, and therefore not true for severe diseases, added Nyberg, a visiting professor at the University of Gothenburg Sahlgrenska Academy, Sweden.
He is not about few common side effects a recipient may experience after receiving the COVID vaccine, but he was discussing about few rare but dangerous cardiac complications after individual doses of the COVID vaccine such as inflammation of the heart muscle or the sack that surrounds it.
Nyberg is co-author of the study which the European Heart Journal published on September 30.
It was designed using data obtained from 8 current or former inhabitants of Sweden who were aged 20 and over during the early days of COVID vaccination in December of 2020 and were followed up to the end of 2022.
Nyberg’s team studied dose to dose, what is called “risk windows” the first minutes after a vaccine shot. They compared the endpoint involving heart health in fully vaccinated patients to the endpoint involving people who, at the same point in the research, had no vaccine at their disposal.
They evaluated risk for some diseases, including inflammation of the heart muscle or sac surrounding it, irregular heartbeat, heart failure, TIA (or ‘mini stroke’) and actual stroke. Both TIA and stroke may occur as a result of a blocked blood flow to the brain area.
The takeaway: “Full vaccination substantially decreased the rate of several additional severe cardiovascular events associated with COVID-19, including heart attack, stroke, and heart failure,” Nyberg stated in a university news release. From many of the outcomes — notably these most severe — the risk of cardiovascular issues was lower following both the first and second dose and even more so after the third dose, the research identified.
Also, in general the risk of the heart events after full vaccination was between the 20 percent and almost round about 30 percent lower than with no shot at all.
The study also confirmed the increased risk of cardiac inflammation one to two weeks after a single COVID shot and it also noted temporary 17 percent higher increase in the risk for extra heartbeats after one dose and 22 percent higher risk after two doses and the increased risk was stronger in men and also in the older people.
Stroke risk dropped after the vaccination though TIA risk rose temporarily by 13 percent one dose mainly in older men.
These particular findings focuses on the protective benefits of full vaccination said Nyber.
