Acute coronary syndrome (ACS) is a clinical syndrome caused by acute myocardial ischemia and a severe stage of coronary atherosclerosis heart disease. The aim of this study was to clarify whether ramipril was a therapeutic agent against monocyte chemoattractant protein 1 (MCP-1), interleukin 18 (IL-18), and interleukin 10 (IL-10) in elderly patients with ACS. A total of 190 subjects including 72 elderly patients with ACS (78.1% male, mean age 67.12 +/- 5.06 years), 60 elderly patients with stable angina pectoris (76.9% male, mean age 68.00 +/- 4.52 years), and 58 healthy volunteers (77.8% male, mean age 65.96 +/- 4.18 years) were recruited into the study. Serum MCP-1, IL-10, and IL-18 were determined in 132 elderly patients by enzyme-linked immunosorbent assay (ELISA) before and after treatment with low doses of ramipril (2.5-5 mg/day), and were determined in 58 healthy volunteers. The levels of serum MCP-1 and IL-18 were much higher in elderly patients with ACS than those in elderly patients with SAP and healthy volunteers. After treating with ramipril, the levels of MCP-1 and IL-18 were decreased in elderly patients with ACS. Moreover, ramipril significantly increased serum IL-10 in elderly patients with ACS. Ramipril plays an important role in elderly patients with ACS. With decreasing MCP-1 and IL-18, it can ameliorate cytokine-associated cardiac damage. This study may provide a new recognition of angiotensin-converting enzyme inhibitor for the treatment of ACS.

Studies suggested that the activation of the coagulation system and inflammation mutually may reinforce each other in some cases. In this study, we test the plasma tissue factor (TF) and interleukin 18 in patients with coronary heart disease (CHD) before and after treatment and aim to determine whether this relationship exists in patients with CHD. The levels of plasma TF and IL-18 from 118 patients with CHD were determined by enzyme-linked immunosorbent assay. One hundred and eighteen patients were divided into acute coronary syndrome (ACS) group (61 cases) and stable angina pectoris group (51 cases). Upon admission, patients with ACS showed significantly higher levels of plasma TF and interleukin 18 compared with those having stable angina (P < 0.01), and the levels decreased after treatment; levels of plasma TF and interleukin 18 of patients with ACS were closely and positively correlated (r = 0.74, P < 0.01); after 7 days of treatment, the correlation decreased (r = 0.53, P > 0.05); and after 1 month of treatment, no significant correlation can be detected between the two (r = 0.18, P > 0.05). The results suggest that levels of plasma TF and interleukin 18 are significantly increased in patients with ACS, and there is significant correlation between the two, indicating an interaction between inflammation and coagulation in patients with ACS and an important role of these two in the occurrence and development of such disease.

Cardiovascular diseases, and in particular coronary artery disease (CAD), are the leading causes of death in Europe and represent around 50% of overall mortality. Numerous cardiovascular markers have been proposed in relation to cardiovascular risk prediction, in relation to cardiac and vascular and cerebral events. Chemokines which regulate immune cell vascular chemotaxis, including CCL5/RANTES are points of great interest. We hypothesized that chemokine RANTES level measured in peripheral blood may be associated with severity of atherosclerosis in patients with stable angina undergoing coronary angiography. RANTES and interleukin 18 (IL-18) levels were measured by ELISA. Classical and novel cardiovascular risk factors like brachial flow mediated dilation and intima-media thickness were analyzed in the context of chemokine levels and severity of atherosclerosis. Study included 62 consecutive patients with coronary atherosclerosis demonstrated by coronary angiography, (mean age 59.3 years (S.D. = 7.4)), divided into two groups: group I with lower severity of atherosclerosis, (n = 45) and group 2 with severe CAD (n = 17) based on coronary angiography. Groups were well balanced for classic risk factors for atherosclerosis. Mean RANTES level were significantly higher in patients in group I (67.9 ng/ml, S.E.M. = 3.97) than in group II (50.5 ng/ml, S.E.M. = 7.49; P = 0.03). In contrast, IL-18 levels were similar in both groups (255 pg/ml in group I and 315 pg/ml, S.E.M. = 40.91 in group I, P = 0.12), as well as hsCRP concentration (3.45 S.E.M. = 2.66 ng/ml and 4.69 ng/ml S.E.M.= 1.64 ng/ml respectively; P = 0.47). Flow-mediated dilatation (FMD) values have been significantly lower in group II than in group I (6.31; S.E.M. = 0.61; vs 4.41; S.E.M. = 0,56, respectively, P = 0.026), while nitroglycerine-mediated dilatation (NMD) did not differ, indicating more pronounced endothelial dysfunction. No significant correlations between chemokine RANTES levels and intima-media thickness (IMT), FMD measurements have been found in the total population studied. Chemokine RANTES level could become a useful marker of severity of coronary artery disease. Its lower levels were observed in patients with more diffuse disease. Elevated level of chemokine RANTES in patients with stable angina pectoris may evaluate patients to high risk group in plaque formation at early stages of atherosclerosis.
