Digital health intervention is beneficial in increasing the survival rate of patients with cardiovascular disease, according to a published meta-analysis in the Mayo Clinic Proceedings. Researchers tested 24,000 patients for the for the last 25 years.
Digital health interventions or telemedicine involves the use of email reminders, SMS text messaging, mobile apps and monitoring data. They help reduce relatively the risk of death due to cardiovascular disease by at least 40 per cent which is considered a much better alternative than taking antihypertension drugs, statins and aspirin.
On the whole, digital health interventions were found to help in weight reduction, BMI, BP and low-density lipoprotein (LDL) cholesterol. These conditions can contribute to cardiovascular disease but do not always mean a cardiovascular disease risk.
Digital health interventions do not always yield the same results, either. The different tools were evaluated by the researchers and they discovered that web-based; i.e. telemedicine interventions and SMS to be the most effective. Whereas, data monitoring and emails were the least effective. Data monitoring was found to be the most beneficial for the reduction of diastolic blood pressure.
Although meta-analysis grabs some promise, it does not tell the whole story though, researchers warn.
