Many non-invasive imaging techniques are available for the evaluation of patients with known or suspected coronary heart disease. Among these, computed-tomography-based techniques allow the quantification of coronary atherosclerotic calcium and non-invasive imaging of coronary arteries, whereas nuclear cardiology is the most widely used non-invasive approach for the assessment of myocardial perfusion. The available single-photon-emission computed tomography flow agents are characterised by a cardiac uptake proportional to myocardial blood flow. In addition, different positron emission tomography tracers may be used for the quantitative measurement of myocardial blood flow and coronary flow reserve. Extensive research is being performed in the development of non-invasive coronary angiography and myocardial perfusion imaging using cardiac magnetic resonance. Finally, new multimodality imaging systems have recently been developed bringing together anatomical and functional information. This article provides a description of the available non-invasive imaging techniques in the assessment of coronary anatomy and myocardial perfusion in patients with known or suspected coronary heart disease.

Coronary heart disease is a global malady and it is the leading cause of death in the United States. Chronic stable angina is the most common manifestation of coronary heart disease and it results from the imbalance between myocardial oxygen supply and demand due to reduction in coronary blood flow. Therefore, in addition to lifestyle changes, commonly used pharmaceutical treatments for angina (nitrates, β-blockers, Ca2+ channel blockers) are aimed at increasing blood flow or decreasing O2 demand. However, patients may continue to experience symptoms of angina. Ranolazine is a relatively new drug with anti-anginal and anti-arrhythmic effects. Its anti-anginal mechanism is not clearly understood but the general consensus is that ranolazine brings about its anti-anginal effects by inhibiting the late Na+ current and the subsequent intracellular Ca2+ accumulation. Recent studies suggest other effects of ranolazine that may explain its anti-anginal and anti-arrhythmic effects. Nonetheless, clinical trials have proven the efficacy of ranolazine in treating chronic angina. It has been shown to be ineffective, however, in treating acute coronary syndrome patients. Ranolazine is a safe drug with minimal side effects. It is metabolized mainly in the liver and cleared by the kidney. Therefore, caution must be taken in patients with impaired hepatic or renal function. Due to its efficacy and safety, ranolazine was approved for the treatment of chronic angina by the Food and Drug Administration (FDA) in 2006.

Aim. To analyze the results of different tactics of single-stent endovascular treatment among patients with coronary heart disease (CHD) and coronary artery bifurcation lesions (CABL). Material and methods. The study included 135 CHD patients with CABL. All participants were divided into 2 groups: Group I (n=77; 58,3 %) consisted of patients who underwent coronary artery (CA) main branch (MB) stenting and subsequent kissing balloon angioplasty of a CA side branch (SB). Group II (n=55) included patients with “genuine” CABL, who underwent only MB stenting with SB protection, but without SB balloon angioplasty. Results. In all 132 CABL patients, drug-eluting stents were successfully implanted, with technical effectiveness of 100 % and in-hospital survival of 100 %. Clinical outcomes were similar in both groups, with no major cardiovascular events registered. At the same time, such an important angiographic index as SB diameter was significantly higher in Group I, compared to Group II. At later stages, Group II patients required SB angioplasty and demonstrated habitual angina symptoms, ischemic electrocardiographic (ECG) changes, and slow SB blood flow (TIMI grade <III) after CA MB stenting. Conclusion. MB stenting of CA bifurcation without SB kissing balloon angioplasty cannot be recommended to all CABL patients. Development of habitual angina symptoms, ischemic ECG changes, and slow SB blood flow (TIMI grade <III) often requires subsequent SB kissing balloon angioplasty.
