Scientists at the University of California conducted a three-year study that proved the benefits of the Hello Heart program for controlling blood pressure. The results can be seen in the JAMA Network Open magazine.

The study involved more than 28 thousand people with hypertension aged 43 to 58 years. For three years, the Hello Heart program monitored the blood pressure of the participants and automatically sent the data to the mobile application. Based on this information, it provided advice on how to improve blood pressure, for example, through diet or exercise.

The results showed that 85% of participants with stage II hypertension had a decrease in systolic pressure, which measures the force of blood acting on the walls of the arteries. The app also helped people with less serious illnesses: within a year, 70% of participants with stage I hypertension also improved their condition.

The Hello Heart app is currently only available to members of employer-sponsored wellness programs. Because of this, employees of companies where Hello Heart is not included in insurance cannot use the program.

The researchers noted that the study participants were middle-aged and earned the national average income. Therefore, it is difficult to determine whether the program would help the elderly or patients without health insurance.

According to a study by the American Heart Association, nearly half of adults in the United States have high blood pressure, but only a third of them try to control it. Scientists predict that mobile technology could improve the situation by automating the prevention of heart disease.
