This study characterized the effects of regular green tea (GT) and hot water (HW) ingestion on systolic blood pressure (SBP), diastolic blood pressure (DBP), pulse pressure (PP), and left ventricular hypertrophy (LVH) in two equal, sex‐ and age‐matched groups; Grp1 and Grp2 (n = 100 each; age 53 ± 4 years) of hypertensive patients. This evidence concerns the gene CYTH3 and left ventricular hypertrophy.
