Relationship Of Pulse Pressure With Acute Myocardial Infarction And Ischemic Stroke

PurposeTo discuss the difference of blood pressure between AMI patients and ICS patients both with hypertension history.MethordsA case-control study was performed to 200 patients(100AMI patients and 100 ICS patients), with t test,X2 test, rank transformation nonparametric test. ResultsPrevalence of ICS and AMI increased with accessending of BP level, patients in AMI group with BP 2 level was more than ICS group, patients in ICS group with BP 3 level was more than AMI group; In addition, prevalence of ICS and AMI increased with PP, patients in ICS group were significantly more than AMI group as PP above 56mmgh (u=2.34,P<0.05); Isolated systolic hypertension can be a predictor of risks o ICS (X2=6.87,P<0.05).Unstablity of BP before onset can be a predictor of risks of AMI and ICS, especially to ICS (X2=7.8 P<0.05).ConclusionPrevalence of ICS and AMI has a trend of increase with BP level and PP in high BP populations. Isolated systolic hypertension shows more pathogenic effect to ICS than AMI. Unstablity of BP may induce ICS.
