    ¡¾Abstract¡¿ AIM: To investigate the correlation between cardiac function and pulse pressure (PP) in patients with acute myocardial infarction (AMI). METHODS: One hundred and fortyª²one patients were divided into two groups: (A): Lower pulse pressure 4.0-5.3 kPa (30-40 mmHg) group (n=70), and (B): Higher pulse pressure 6.6-8.0 kPa (50-60 mmHg) group (n=71). The differences in age, heart function, heart rate, serum lipid, systolic blood pressure and diastolic blood pressure between the two groups were compared. RESULTS: The age [(68.7¡À12.2) year vs (62.6¡À12.2) year], systolic blood pressure [(17.8¡À1.9) kPa vs (14.4¡À2.0) kPa], diastolic blood pressure [(10.6¡À1.8) kPa vs (9.8¡À1.9) kPa] and apolipoprotein B (apo B) [(0.86¡À0.2) mg/L vs (0.72¡À0.2) mg/L] were higher, and the cardiac function [(2.0¡À0.8) level vs (1.7¡À0.8) level] was worse in patients with higher pulse pressure group than those in patients with lower pulse pressure (P<0.05-P<0.01). Compared with those with lower pulse pressure, Female¡¯s proportion (35.2% vs 17.1%), lowª²density lipoprotein cholesterol (LDLª²C) [(2.76¡À0.8) mmol/L vs (2.49¡À0.5) mmol/L], highª²density lipoprotein cholesterol (HDLª²C) [(1.31¡À0.4) mmol/L vs (1.15¡À0.5) mmol/L] and apolipoprotein A (apo A) [(1.10¡À0.4) mg/L vs (0.97¡À0.2) mg/L] was higher in patients with higher pulse pressure (P all<0.05). No difference was found in heart rate [(82.3¡À19.8) beat/min vs (78.0¡À20.1) beat/min] between the two groups (P>0.05). CONCLUSION: The AMI patients with higher pulse pressure tend to be elders, have worse cardiac function and higher blood pressure. ......
