Timely Treatment

Over the past few decades, a steady rise in the incidence, morbidity and mortality from cardiovascular diseases has been observed throughout the world. The most common pathology is coronary heart disease (CHD) which, in addition, is responsible for chronic heart failure in more than one third of the cases. Patients with coronary heart disease are in need of early diagnosis and timely treatment. This article provides an overview of current scientific literature concerning anatomy of coronary vessels, their age-related changes, and modern radiological diagnostic methods of the lesions associated with coronary artery disease.

Background Although many observational studies have shown an association between plasma homocysteine levels and cardiovascular diseases, controversy remains. In this study, we estimated the role of increased plasma homocysteine levels on the etiology of coronary heart disease and acute myocardial infarction. Methods A two-sample Mendelian randomization study on disease was conducted, i.e. “coronary heart disease” ( n = 184,305) and “acute myocardial infarction” ( n = 181,875). Nine single nucleotide polymorphisms, which were genome-wide significantly associated with plasma homocysteine levels in 57,644 subjects from the Coronary ARtery DIsease Genome wide Replication and Meta-analysis (CARDIoGRAM) plus The Coronary Artery Disease (C4D) Genetics (CARDIoGRAMplusC4D) consortium genome-wide association study and were known to be associated at p < 5×10–8, were used as an instrumental variable. Results None of the nine single nucleotide polymorphisms were associated with coronary heart disease or acute myocardial infarction ( p > 0.05 for all). Mendelian randomization analysis revealed no causal effects of plasma homocysteine levels, either on coronary heart disease (inverse variance weighted; odds ratio = 1.015, 95% confidence interval = 0.923–1.106, p = 0.752) or on acute myocardial infarction (inverse variance weighted; odds ratio = 1.037, 95% confidence interval = 0.932–1.142, p = 0.499). The results were consistent in sensitivity analyses using the weighted median and Mendelian randomization-Egger methods, and no directional pleiotropy ( p = 0.213 for coronary heart disease and p = 0.343 for acute myocardial infarction) was observed. Sensitivity analyses confirmed that plasma homocysteine levels were not significantly associated with coronary heart disease or acute myocardial infarction. Conclusions The findings from this Mendelian randomization study indicate no causal relationship between plasma homocysteine levels and coronary heart disease or acute myocardial infarction. Conflicting findings from observational studies might have resulted from residual confounding or reverse causation.

Abstract Background Peripheral artery disease (PAD) is recognized as a significant predictor of mortality and adverse cardiovascular outcomes in patients with coronary heart disease (CHD). In fact, coexisting PAD and CHD is strongly associated with a greater coronary event recurrence compared with either one of them alone. High-density lipoprotein (HDL)-mediated cholesterol efflux capacity (CEC) is found to be inversely associated with an increased risk of incident CHD. However, this association is not established in patients with PAD in the context of secondary prevention. In this sense, our main aim was to evaluate the association between CEC and PAD in patients with CHD and whether the concurrent presence of PAD and T2DM influences this association. Methods CHD patients (n = 1002) from the CORDIOPREV study were classified according to the presence or absence of PAD (ankle-brachial index, ABI ≤ 0.9 and ABI > 0.9 and < 1.4, respectively) and T2DM status. CEC was quantified by incubation of cholesterol-loaded THP-1 cells with the participants' apoB-depleted plasma was performed. Results The presence of PAD determined low CEC in non-T2DM and newly-diagnosed T2DM patients. Coexisting PAD and newly-diagnosed T2DM provided and additive effect providing an impaired CEC compared to non-T2DM patients with PAD. In established T2DM patients, the presence of PAD did not determine differences in CEC, compared to those without PAD, which may be restored by glucose-lowering treatment. Conclusions Our findings suggest an inverse relationship between CEC and PAD in CHD patients. These results support the importance of identifying underlying mechanisms of PAD, in the context of secondary prevention, that provide potential therapeutic targets, that is the case of CEC, and establishing strategies to prevent or reduce the high risk of cardiovascular events of these patients.

Background.Matrix metalloproteinases, such as stromelysin-1, are implicated in the pathogenesis of coronary artery disease (CAD) and acute myocardial infarction (MI). A 5A/6A promoter polymorphism can regulate the transcription of the stromelysin-1 gene in an allele-specific manner. Evidence has been presented that the 6A allele is associated with the progression of coronary heart disease (CHD). In contrast, the 5A allele may be linked to the risk of MI.Results.To analyse the relation of the 5A/6A polymorphism with the risk and severity of CHD and the risk of MI, a case-control study of 515 healthy controls and 1848 participants who underwent coronary angiography for diagnostic purposes was conducted. In the total sample, the mean CHD scores—according to Gensini—were different between 5A/6A genotypes: 5A5A homozygotes had the lowest, 6A6A genotypes the highest and 5A6A heterozygotes intermediate scores. These differences were even more pronounced when the participants were restricted to individuals with a high coronary risk profile (high apoB levels, high Lp(a) levels, high glucose levels, combinations of either high apoB and Lp(a) levels or high apoB, Lp(a) and glucose plasma levels). Mean values were used as cut points for high-risk populations, respectively. In contrast, the 5A allele was not associated with the risk of CHD or MI. Even when angiographically controlled individuals without MI were compared with MI patients in subpopulations of participants with no, single, double and triple vessel disease, the frequencies of the 5A/6A and/or the 5A5A genotypes were not higher in each subgroup, respectively.Conclusions.The present results do not confirm an association of the 5A allele with the risk of MI, observed in another investigation, but strengthen the hypothesis of earlier studies that the 6A allele is a disease marker for progression of coronary heart disease. Further investigations should evaluate whether 6A allele carriers and especially 6A homozygotes might benefit from a more aggressive therapy against CHD progression.

Atherosclerosis Prevention

PEDIATRIC GENESIS OF ATHEROSCLEROSIS Atherosclerosis results from a variety of pathophysiologic disturbances, some currently recognized, and many undoubtedly not yet recognized, which in aggregate are identified as risk factors. Genetic and environmental influences conjointly affect the incidence and the severity of these risk factors and, thus, coronary heart disease (CHD) risk. Prophylaxis should be designed to prevent or retard the development of arterial plaques. This suggests that diagnostic and preventive efforts should begin in childhood. Eating habits are also probably established in childhood, allowing their early modification. The atherosclerotic plaque appears to have its genesis in childhood. The data from wartime autopsies confirm the presence of mature atherosclerotic lesions by the end of the second decade and emphasize the importance of primary atherosclerosis prevention beginning in the first and second decades. While there are clearly genetic factors in CHD, variation in rates in differing geographic areas appears less likely to be related to genetic than to environmental differences. Marked differences in plasma cholesterol levels are found in children in different geographic areas, generally paralleling pediatric cholesterol and saturated fat intake and the incidence of adult coronary heart disease. The relationships of elevated total plasma cholesterol levels to the incidence of coronary heart disease are clearly established in adults.

In the past 20 years, considerable change has occurred in the profile of congenital heart disease regarding both diagnosis and treatment. The profile has changed from older to younger patients; the essence of this change has been from pediatric to infant to neonatal cardiology. There has been a shift from palliative to more definitive surgical procedures and a change from invasive (cardiac catheterization) to noninvasive (echocardiography) diagnostic methods. The profile has changed from definitive surgical treatment limited to simple lesions to surgical treatment of the most complex lesions. There has been steady improvement in the recognition of cases of congenital heart disease. Of all children admitted to hospitals for treatment of congenital heart disease, the portion less than three days of age has increased from 24% in 1969 to 1972 to 33% in 1982 to 1986.

Cardiovascular diseases caused by atherosclerosis (coronary artery disease, cerebrovascular pathology, etc.) are responsible for 40-50% of all deaths in adults. Of particular concern to clinicians is the emerging unfavorable tendency to "rejuvenate" these diseases. Currently, the fact that atherosclerosis (AS) begins to form in childhood and adolescence is indisputable.
