A case report of superior vena cava obstruction.

We report herein an 83-year-old gentleman with lung cancer who presented with nausea, complete atrioventricular (AV) block and presyncope. Despite a present temporary pacemaker, which had been inserted through the femoral vein 5 days previously, the patient had asystole attacks that resolved with atropine administration. Coronary angiography demonstrated no critical stenosis.

Angiographic evaluation of the radial artery diameter in patients who underwent coronary angiography or coronary intervention.

Objectives: The aim of this study was to determine the radial artery diameter of patients through angiography and evaluate the feasibility of using wider sheaths for radial interventions. In addition, any parameters that could affect the radial artery diameter were also evaluated.

Background: The radial artery is a suitable, beneficial route for coronary procedures and is considered a good alternative to transfemoral access.

Quantitative evaluation improves specificity of myocardial perfusion SPECT in the assessment of functionally significant intermediate coronary artery stenoses: a comparative study with fractional flow reserve measurements.

Objective: Myocardial perfusion SPECT (MPS) is a noninvasive method commonly used for assessment of the hemodynamic significance of intermediate coronary stenoses. Fractional flow reserve (FFR) measurement is a well-validated invasive method used for the evaluation of intermediate stenoses. We aimed to determine the association between MPS and FFR findings in intermediate degree stenoses and evaluate the added value of quantification in MPS.

The particular interactions of the traditional cardiovascular risk factors with different circulating specific leukocyte subtype counts in blood: an observational study.

Objective: The pathogenesis of atherosclerosis is multifactorial, however the impact of inflammatory cells in this process is well known. Different traditional cardiovascular risk factors (CVRFs) may have specifically different effects on leukocyte subtype. Thus, these special interactions may induce different vascular involvement forms due to the altered endothelial damage and vascular repair mechanisms.

[The relation of serum monocyte chemoattractant protein-1 level with coronary atherosclerotic burden and collateral degree in stable coronary artery disease].

Objectives: We investigated whether serum monocyte chemoattractant protein-1 (MCP-1) level predicted coronary atherosclerotic burden in patients with stable coronary artery disease and its relationship with coronary collateral grade.

Study Design: We prospectively included 196 patients (103 males, 93 females; mean age 59 ± 11 years) who underwent coronary angiography for stable angina pectoris. Serum MCP-1 levels were determined before coronary angiography.
