BACKGROUND: A role of CD14 receptor in the inflammatory response is stimulation of monocytes and endothelial cells by lipopolysaccharide of Gram-negative bacteria. The reports about association of progression of atherosclerosis with CD14 gene polymorphism in different populations are conflicting. AIM: To assess if T to C exchange at position 159 of the CD14 gene correlates with age at the onset of first myocardial infarction (MI), severity of coronary atherosclerosis and number of risk factors in MI survivors in a local community characterised by high morbidity of cardiovascular diseases and whether this genotyping could be helpful in identifying patients with a high risk of MI at young age and beyond low number of risk factors. METHODS: Fifty-seven MI survivors (75.5% males) from 98 consecutive patients (pts) with coronary artery disease were included. The genotypes in position 159 of the CD14 gene were determined by polymerase chain reaction. The medical history concerning diabetes mellitus, arterial hypertension, dyslipidaemia, smoking and obesity was taken from every participant. Gensini score (GS) was calculated on the basis of coronarography. Age at first MI, value of GS and number of risk factors were analysed variables. The pts were divided into the decades of life, according to cumulated number of risk factors and into the terciles according to GS. Distribution of ages at first MI, pts with different number of risk factors and percent of pts belonging to determined terciles of GS were compared between subgroups with genotype CC and CT, TT. RESULTS: The CC genotype was detected in 25 (43.8%) pts, CT in 30 (52.6%) and TT in 2 (3.6%). Age at first MI ranged from 40 to 75 years, mean 58.7+/-7.23, values of GS ranged from 0 to 154, mean 48.6+/-25.7, and number of risk factors from 0 to 4, mean 1.92+/-0.99. No significant differences in distribution of ages at first MI, values of GS or number of risk factors were found between patients with CC and with CT or TT genotype in position 159 of CD14 receptor genotype. CONCLUSION: These data indicate that screening for CD14 159C/T polymorphism is unlikely to be a useful tool for risk assessment of MI at young age, independently of low number of risk factors, in a population with high morbidity from cardiovascular diseases.

We present a case of 29-year-old male, with coronary artery disease in mother's history, after suicidal poisoning with 30 g of rifampicin, who presented severe chest pain, ST elevations in ECG, low values of blood pressure and elevated troponin I. Echocardiography revealed generalised hypokinesia, and depressed contractility--left ventricle ejection fraction was 7%. Urgent coronary angiography has shown normal epicardial arteries with slow contrast inflow. The toxic properties of rifampicin as well as hypotension due to dehydration are considered reasons of symptoms in the presented case.

UNLABELLED: Psychiatric abnormalities (PA) are often observed in patients (pts) in the Coronary Care Units. The origin of such abnormalities is not always clear, but it is known that they may aggravate patients status and interfere with further treatment. The aim of this study was to analyze the factors potentially predisposing to the occurrence of PA in pts with acute myocardial infarction (AMI). MATERIAL: The study group consisted of 200 consecutive pts hospitalized due to AMI. In 63 of them (Group A) the in-hospital course was complicated by PA (agitation, anxiety, hallucinations). Sex- and age-matched 63 pts of the remaining 137 pts which had not PA were control group (Group B). METHODS: The data related to coronary artery disease history, AMI diagnosis and treatment were withdrawn from hospital reports. Second group of parameters was focused on history of central nervous system (CNS) diseases, vision and audition ability, stimulant or drug addiction. The data about patient's employment and familial status, level of education, self-estimation of quality of life (QoL) in hospital were the third group of parameters. The second and third group of data were questionnaire-based information. RESULTS: There were no significant differences between groups in arrhythmias, localization of AMI, percentage of pts with high level of education, neither living alone or with family, jobless, retired or employed ones. Also self-evaluation of QoL was distributed similarly. The parameters which differed Group A versus Group B were respectively: history of CNS diseases (48% vs 20%, p<0,05), in particular--CNS traumas (18% vs 2,3%, p<0,05) and ischemic episodes (10% vs 0%, p = 0,039), thrombolytic (non-percutaneous interventional) treatment 23,8 vs 4,6%, p<0,05), handicap of visual ability (16% vs 0%, p--0,012), nicotinism (30% vs 9,1%, p<0,05), left ventricle ejection fraction <40% (34% vs 5%, p<0,05), treatment with atropine (12,7% vs 0%, p = 0,012) or amiodarone (16,7% vs 0%, p = 0,037). CONCLUSION: History of neurological diseases, thrombolytic treatment, left ventricle ejection fraction <40%, handicap of visual ability, nicotinism and amiodarone or atropine in pharmacological treatment are factors which may be helpful to predict PA in pts with AMI. Cumulation of such factors increases a risk of occurrence of transient psychiatric abnormalities. Proper psychoactive pretreatment should be applied in pts with such profile in purpose to avoid behavior related complications.
