ABSTRACT
Coronary microcirculation regulates coronary blood flow volume via systolic and diastolic function and af—fects myocardial perfusion ,which possesses deep influence on prognosis of patients with coronary heart disease and cardiomyopathy .Along with developments of recent noninvasive and invasive techniques , continuous updates of medication area ,understanding of coronary microvascular dysfunction keeps going deeper .The present article made following review on new research progress of coronary microvascular dysfunction .
ABSTRACT
To compare therapeutic effect of dibutyryl cyclic adenosine monophosphate calcium (DCAMC) on chronic heart failure (CHF) between different administration route .Methods :The 98 CHF patients were ran‐ domly and equally divided into intravenous drip (i .v.gtt) group and intramuscular injection group (i.m .) group , both groups received DCAMC via corresponding administration route based on routine anti heart failure treatment for 10d.Plasma level of N terminal pro brain natriuretic peptide (NT‐proBNP) ,left ventricular end diastolic dimen‐sion (LVEDd) ,LVEF before and after treatment ,and incidence of adverse reactions were observed and compared between two groups .Results :Compared with before treatment , there were significant reductions in plasma NT‐proBNP level [i.v.gtt group :(6846.23 ± 3856. 01)pg／ml vs.(2285.69 ± 2023.79)pg／ml ,i .m .group :(6151. 50 ± 5160.09) pg／ml vs.(2568.37 ± 2488.51)pg／ml] and LVEDd [i.v.gtt group :(4.78 ± 0.44 )cm vs.(4. 69 ± 0.43) cm ,i.m .group :(4.97 ± 0.64)cm vs .(4. 88 ± 0.62) cm] ,and significant rise in LVEF [i.v.gtt group :(59.49 ± 4.64)% vs.(60. 67 ± 4. 52)%,i.m.group :(57.67 ± 7.19)% vs.(58.94 ± 7.05)%] in two groups after treatment , P＝0.001 all.There were no significant difference in above indexes between two groups before and after treatment , P＞0. 05 all.There was no significant difference in incidence rate of adverse reactions between two groups , P＝1.000. Conclusion :DCAMC can improve cardiac function in CHF patients .Therapeutic effect of local intramuscular injection is equal with that of intravenous drip .
ABSTRACT
H type hypertension is essential hypertension complicated elevated plasma homocysteine level ,which ac-counts for about 75% in Chinese adults with hypertension and is closely related to cerebral stroke and other cardio-vascular diseases .Lowering homocysteine level in patients with hypertension possesses important significance for preventing stroke .
