Age and blood pressure of patients of acute myocardial infarction (MI) and acute angina (AA)

Groups	Age (years)	Blood pressure (mm Hg)	Serum cholesterol (mg/dl)
Group (1)	60 ± 10	138 ± 10/77 ± 4	405.00 ± 76.70
Group (2)	60 ± 10	115 ± 5/80 ± 9	255.40 ± 41.53
Group (3)	55 ± 10	126 ± 14/81 ± 10	354.90 ± 71.09
Group (4)	55 ± 10	116 ± 5/77 ± 5	252.70 ± 42.51

Effect of L-arginine (Arg) administration on the levels of serum cholesterol in the patients of MI and AA are also reported. Serum cholesterol levels in patients was estimated by the method of Sperry and Webb. Values for cholesterol levels are presented as mean ± SD. Statistical significance of the groups has been determined by one way ANOVA followed by Newmann-Keul's multiple comparison test. p values of serum cholesterol level are Group 1 vs. Group 2 p < 0.005; Group 3 vs. Group 4 p < 0.05.
