LDL subfractions in patients with myocardial infarction: effect of smoking and beta-blocker treatment.

The aim of the present case-control study was to estimate, by density gradient ultracentrifugation, LDL heterogeneity in myocardial infarction, and to evaluate the effect of smoking and beta-blocker treatment on LDL subfraction profile. Our results show that patients who survive myocardial infarction have an abundance of small, dense LDL in their plasma, compared with controls. Patients who were on beta-blockers and those who smoked showed a more atherogenic LDL subfraction profile than the rest.

High incidence of dyslipidaemia in the offspring of Greek men with premature coronary artery disease.

Aim: The present study aimed to assess the incidence and type of lipid disorders in the offspring of young Greek coronary patients.

Methods: One hundred and ninety-three children and youngsters were divided into two groups. Group A consisted of 104 children whose fathers had sustained a myocardial infarction before the age of 55 years.

Plasminogen activator inhibitor 1 is elevated in the children of men with premature myocardial infarction.

To assess whether plasminogen activator inhibitor 1 (PAI-1) activity is elevated in the progeny of young coronary men, 193 young subjects were recruited and divided into two groups. Group A consisted of 104 children whose fathers had suffered a myocardial infarction before the age of 55 ("cases"). Eighty-nine young subjects matched for age, sex, body mass index (BMI) and smoking habits without familial history of coronary artery disease (CAD) served as controls (group B).

Fibrinogen in the offspring of men with premature coronary artery disease.

We examined whether the levels of fibrinogen are elevated in the offspring of middle-aged coronary patients. One hundred and seventy-six young subjects were divided into two groups. Group A consisted of 100 children and youngsters (mean age 17 +/- 6 years) whose fathers had sustained a myocardial infarction under the age 55 years without associated history of diabetes mellitus or hypertension.

HLA antigens in Greek patients with cholelithiasis.

The distribution of HLA-A and B antigens was studied in 100 patients with cholelithiasis and in 202 healthy individuals all of Greek origin. An increased frequency of HLA-Aw19 was found in patients (33 per cent) compared with controls (22 per cent) (p less than 0.05, RR 1.
