| How can I avoid heart disease or stroke? Posted: 30 Aug 2021 06:59 AM PDT As much as 90% of the risk of a heart attack, stroke, or peripheral arterial disease (PAD) can be explained by smoking, poor eating habits, lack of physical activity, abdominal obesity, high blood pressure, raised blood lipid levels, diabetes, psychosocial factors, or alcohol. These guidelines focus on atherosclerotic cardiovascular disease (CVD), which affects the arteries. As the inside of the arteries become clogged up by fatty deposits, they can no longer supply enough blood to the body. This process is the main cause of heart attacks, strokes, PAD and sudden death where arteries become completely blocked. The most important way to prevent these conditions is to adopt a healthy lifestyle throughout life, especially not smoking, and to treat risk factors. |

| COVID-19 antibody study shows downside of not receiving second shot Posted: 30 Aug 2021 05:18 AM PDT A new study shows that two months after the second Pfizer/Moderna vaccination, antibody response decreases 20 percent in adults with prior cases of COVID-19, and tests how well current vaccines resist emerging variants. The study also showed that prior exposure to SARS-CoV-2 does not guarantee a high level of antibodies, nor does it guarantee a robust antibody response to the first vaccine dose. This directly contradicts the assumption that contracting COVID will naturally make someone immune to re-infection. The findings further support vaccination (and two doses), even for people who have contracted the virus previously. |
