Heart disease can be predicted by both high systolic and high diastolic blood pressure numbers

Blood pressure readings are critical for analyzing and monitoring blood pressure. These tests record blood pressure using two measurements: systolic and diastolic blood pressure. Understanding these numbers is key to controlling blood pressure. The systolic pressure shows how much pressure the blood places on the arteries when the heart beats, while the diastolic blood pressure shows the pressure while the heart is resting between beats. Decades of research have indicated that high systolic blood pressure is more likely than diastolic pressure to predict heart disease, but now, a new study finds that both numbers in blood pressure readings have a strong association with heart attack and stroke risk. Researchers at Kaiser Permanente, a healthcare company in Oakland, CA, carried out the study. "This research brings a large amount of data to bear on a basic question, and it gives such a clear answer," says Dr. Alexander C. Flint. The new study is the largest of its kind. The findings confirmed that systolic pressure has a greater effect, but they also demonstrated that both systolic and diastolic pressure can predict the risk of heart attack or stroke. This analysis, using a very large amount of longitudinal data, convincingly demonstrates that both are important, and it shows that in people who are otherwise generally healthy, lower blood pressure numbers are better." Says, Dr. Deepak L. Bhatt. (Source: www.medicalnewstoday.com)

Pre-op anxiety? Is music a remedy?

Before undergoing an operation, most people experience some form of anxiety. Although this response is common, it is not unproblematic, and treatment often involves a sedative with a whole host of possible side effects. Typically, people receive benzodiazepines — drugs that act as sedatives. But benzodiazepines can cause a number of side effects that may impact breathing, blood flow, and even mood. The power of music in relation to anxiety has been the subject of previous studies. But no study had compared music to benzodiazepines, until now. Experts believe that relaxing music has a very definitive sound. As Southern Medical Journal research states, a tune that involves no lyrics, no significant change in tempo or rhythm, and an estimated 60 beats per minute is the most effective in reducing anxiety. A study was conducted. One group received injections of a benzodiazepine called midazolam 3 minutes before anesthesia. The researchers gave noise canceling headphones to the other group, who listened to a preprogrammed musical track for a total of 3 minutes. The groups then received a peripheral nerve block anesthetic that numbed a specific part of the body. Surprisingly, the results revealed that the changes in preoperative anxiety levels caused by both calming methods to be alike. Doctors also reported similar satisfaction levels. The only real difference was that people who listened to music felt less satisfied than those in the drug group. The researchers believe that this reaction may have been influenced by the participants' not being able to choose the piece of music.
