Good BP, blood sugar levels can prevent heart block

Good BP, blood sugar 
levels can prevent 
heart block

Keeping blood pressure and blood sugar levels under control might prevent a common heart rhythm disorder called "heart block." That's the finding from a new study analyzing data on more than 6,000 people, aged 30 and older, in Finland. In the study, the University of California, San Francisco (UCSF) researchers found that 58 of those people developed heart block over an average follow-up of 25 years.

Heart block, or atrioventricular block, occurs when electrical signals between the heart's four chambers are disrupted. Often felt as a skipped beat, it can lead to the need for a pacemaker. Every 10 millimeter increase in systolic blood pressure resulted in a 22% greater risk of heart block, and every millimeter increase in fasting blood sugar (glucose) resulted in a 19% greater risk, the findings showed. The researchers estimated that 47% of the 58 heart block cases could have been prevented with ideal blood pressure and 11% with normal fasting glucose.

Other factors in the Finnish data associated with increased risk of heart block were older age, being male and having a history of heart attack or heart failure.

The researchers noted that there has been little research on whether lifestyle changes can prevent heart block, probably because the condition is widely treated with pacemakers.

"It is perhaps precisely because pacemakers so successfully and immediately address cases of heart block that we have previously failed to devote more attention to prevention of this important disease," study senior author Dr. Gregory Marcus, a UCSF Health cardiologist, said in a university news release.

"In addition to the prevention and treatment of [heart attack] and heart failure, effective treatment of hypertension and maintenance of normal blood sugars may be useful prevention strategies," he added.

"Given the prevalence of heart block in the adult male population, as well as the multiple risks associated with pacemakers, it would be worthwhile to pursue further research on this connection," Marcus added.

"This new information also may help persuade hypertensive individuals to receive and continue their prescribed treatments," he concluded.

We should all have a blood pressure below 120 over 80 (120/80). This is the ideal blood pressure for people wishing to have good health. At this level, we have a much lower risk of heart disease or stroke.

If your blood pressure is optimal, this is great news. By following our healthy living advice, you will be able to keep it this way.  If your blood pressure is above 120/80mmHg, you will need to lower it.

Most adults in the UK have blood pressure readings in the range from 120 over 80 (120/80) to 140 over 90 (140/90). If your blood pressure is within this range, you should be taking steps to bring it down or to stop it rising any further. Our five top tips will show you how.

The reason why people with blood pressure readings in this range should lower it, even though this is not classified as 'high' blood pressure, is that the higher your blood pressure, the higher your risk of health problems. For example, someone with a blood pressure level of 135 over 85 (135/85) is twice as likely to have a heart attack or stroke as someone with a reading of 115 over 75 (115/75).
