Table 4 Studies on leptin in acute myocardial infarction

From: Elevated serum leptin levels in patients with acute myocardial infarction; correlation with coronary angiographic and echocardiographic findings




Hadi Khafaji et al. 2011 Qatarcurrent study

87 pts: 51 AMI pts + 36 matched control

Leptin level is significantly correlated with BMI, CK, and LVEF. But neither with the type of MI (anterior vs. inferior) nor with the severity of angiographic findings and other echocardiographic parameters.

Yan GT,et al. * 2005 China [28]

AMI and CS pts

Leptin levels of both AMI & coronary atherosclerosis pts are significantly without a significant difference between each other, no correlation for leptin with CRP, TnT & endothelin

Krasnodebski et al. 2010 Poland [24]

58 patients with AMI

Plasma leptin levels in diabetic pts are significantly in acute stage of AMI than in the period of convalescence.

Wallander M,et al. 2008Sweden [29]

181 AMI

Circulating levels of leptin on the first morning after an AMI are associated with the presence of abnormal Glucose tolerance at discharge & with poor long-term prognosis.

Piestrzeniewicz et al. 2007 Poland [31]

40 obese and 40 non-obese men.

Leptinemia is associated with fasting glucose, triglyceride levels, CRP & uric acid & negatively with HDL-C; leptin may be a pathogenetic factor in cardiovascular disease

Taneli et al. 2006 Turkey [30]

35 pts stable angina + 40 STEMI, + 30 control

S. leptin is significantly in both stable angina &STEMI groups. No significant correlation between leptin levels & selected risk factors

Amasyali et al. 2006Turkey [25]

41 pts with AMI have thrombolysis

Failure of reperfusion therapy with streptokinase is significantly in patients with admission plasma leptin ≥14 ng/mL vs. pts with admission plasma leptin <14 ng/mL.

Selvakumar et al. 2005 India [32]

94 pts with acute ST EMI + 46 controls

leptin level is in patients with acute STEMI

Meisel et al. 2001 Isreal [26]

30 pts, AMI

Leptin peaked on the 2nd day of hospitalization with a 2-fold from its baseline level on admission (p < 0.02). On day 3, leptin levels, & were 46%, 9%, &6% above baseline on days 3, 4 and 5, respectively.

Fujimaki et al. 2001 Japan [35]

21 AMI pts 15 control

Hypoleptinaemic AMI pts had significantly plasma LDH vs. normoleptinaemic pts. No differences in other serum markers between normo vs. hyperleptinaemic AMI

Söderberg et al. 1999 Sweeden [33]

62 men with first-ever AMI

High leptin (OR 8.97; 95% CI: 1.73-46.5) & cholesterol (OR 5.18; 95% CI: 1.34-20.0) levels significant risk factors for AMI in a multivariate model

Stejskal et al. 1988 Czech** [34]

16 AMI, 22 unstable angina

Early after the acute coronary event, leptinemia in persons with AMI statistically positively correlated with concentration of interleukine-6 & subsequently of markers of coronary lesion severity (cTnI).
