Difficulties in maintaining potassium homeostasis in patients with heart failure.
Potassium (K) concentration plays a significant role in cell metabolism and membrane excitability. The imbalance of serum potassium is important because it can lead to life-threatening events. Potassium balance may be lost both through the neurohormonal mechanisms involved in cardiovascular diseases and through the drugs used in the treatment of this illness. Avoiding both hypo- and hyperkalemia is beneficial in several cardiovascular diseases, especially heart failure. Electrolyte abnormalities are frequently seen complications in subjects with heart failure. Malignant ventricular arrhythmias and sudden cardiac death are particularly feared complications in K+ instability.

[Plasma insulin, glucose and lipid levels, and their relations with corrected TIMI frame count in patients with slow coronary flow].
OBJECTIVE: High baseline insulin and glucose levels and presence of accompanying dyslipidemia, which are considered in the pathogenesis of metabolic syndrome X, were also observed in patients with cardiac syndrome X, which is similar to metabolic syndrome X in many aspects. In this study we aimed to compare serum insulin, glucose and lipid levels in patients with coronary slow flow which is hypothesized as a subgroup of cardiac syndrome X with those of healthy subjects and determine the relation of corrected TIMI frame count (cTFC) with these levels. METHODS: Forty-six patients with normal epicardial coronary arteries but determined as coronary slow flow in coronary angiography performed because of chest pain and 16 healthy subjects having normal coronary arteries but without coronary slow flow were included in this study. Maximal exercise stress test according to Bruce protocol was performed in all patients. Baseline serum insulin, glucose and lipid levels were measured from venous blood samples of patients in both groups. TIMI 'frame count' method was used for diagnosis of coronary slow flow. The relationship between the degree of coronary slow flow and serum insulin, glucose and lipid levels was investigated. RESULTS: Exercise stress test results of both groups were considered as negative regarding ischemia. There were no differences between 2 groups in serum insulin, glucose and lipid levels. (p>0.05). No relationship were determined by correlations analysis between serum insulin, glucose and lipid levels and corrected TIMI frame count. CONCLUSION: Normal values of insulin, glucose and lipid levels in patients with coronary slow flow and lack of their relation with cTFC support the opinion that coronary slow flow is a separate from the cardiac syndrome X clinical entity.

Treatment strategies in myocardial bridging: a case report.
Myocardial bridging is one of the nonatherosclerotic causes of coronary artery disease and is characterized by muscles overlying the intramyocardial course of a major epicardial coronary artery segment, leading to systolic compression. Myocardial bridging is considered a benign condition in most cases, but has been associated with serious cardiac events such as myocardial infarction and sudden death. We discuss the case of a 63-year-old man who was admitted to our hospital with effort-induced angina, bradycardia, and left ventricular hypertrophy on electrocardiogram. On coronary angiography, we found significant myocardial bridging with total occlusion in the left anterior descending artery during systole. In patients with myocardial bridging, symptoms often manifest during exercise and with tachycardia. But it is interesting to note that our patient was bradycardic and became symptomatic with minimal effort. Thus, we thought that these emphasized its significance and affected treatment strategy.
