Caffeine, hypertension, cardiovascular disease, and stroke:
Caffeine may increase risk of premature death in patients with hypertension, cardiovascular disease, and stroke. According to James J. E., caffeine through its daily consumption from a variety of sources (coffee, teas, soft drinks, chocolate and medicines), may have an impact on cardiovascular risk. This fact is related to the evidence found the scientific literature about the ability of caffeine to increase resting blood pressure (BP) in adults by about 4/2 mmHg. However, this increase in BP could be responsible for premature deaths of about 14% for coronary heart disease and 20% for stroke. (31)
