Investigating the risks COVID-19 poses to people with high blood pressure

Researchers are working to understand the specific risks that COVID-19 poses to people with cardiovascular disease, which is an umbrella term that includes conditions such as high blood pressure (hypertension). One such group of researchers has found that high blood pressure was more common in COVID-19 patients who developed heart injury (also known as myocardial or cardiac injury). Of the 82 patients who developed heart injury in a study conducted in 416 patients hospitalized with COVID-19 in China, 59.8% had hypertension.

The study identified heart injury as being a common complication in patients who developed COVID-19, with 19.7% of patients in the study developing it. Concerningly, it also appears to be a deadly complication as 51.2% of the patients who developed heart injury died, compared with only 4.5% of the patients who did not show signs of heart injury.

People with high blood pressure appear to be at increased risk from COVID-19

On March 17, 2020, the National Institute of Health in Italy released a report stating that 99% of patients with COVID-19 who had died in Italy had a pre-existing condition. More specifically, 76.1% of the patients who died in Italy had high blood pressure.

The Chinese Centers for Disease Control has published case reports that are reported to indicate people with pre-existing conditions, including hypertension, are at increased risk of developing severe COVID-19. Studies from China that have already been published in the scientific literature report that:

Metoprolol Succinate vs Tartrate: What's the difference between them?

Metoprolol is available as two different salts: metoprolol tartrate and metoprolol succinate.

The main difference between metoprolol tartrate and metoprolol succinate is that metoprolol tartrate is only available as an immediate-release tablet which means it must be taken several times per day, whereas metoprolol succinate is an extended-release tablet that can be taken once a day. As a result, there are differences in the dosages and indications for both metoprolol tartrate and metoprolol succinate and they are not considered interchangeable. Continue reading

How quickly does propranolol work?

When propranolol is used to relieve performance, social, or situational anxiety, it works quickly, usually within 30 to 60 minutes to help relieve physical symptoms of anxiety such as flushing, shaking, sweating, trembling, and an elevated heart rate. It is unlikely to relieve the mental symptoms of anxiety (such as mental fog or blankness), but generally relieving some of the physical symptoms improves the mental symptoms. Its effects last for 3 to 4 hours. Continue reading
