REVIEW
R Andrew Archbold
Cardiologists in the UK use clinical practice guidelines from the National Institute for Health and Care Excellence (NICE) and from the European Society of Cardiology (ESC) to aid clinical decision-making. This review compares their recommendations regarding stable angina. NICE's diagnostic algorithm changed clinical practice in the UK, with most cardiologists moving from the exercise ECG towards newer, more accurate imaging modalities such as CT and MRI for diagnostic testing in patients with a low or medium probability of coronary artery disease (CAD), and directly to invasive coronary angiography in patients with a high probability of CAD...

BACKGROUND: Heart rate turbulence (HRT) assessment is used as noninvasive method based on physiological sinus node response to the premature ventricular beat. Blunted HRT may indicate the autonomic nervous system impairment and can be helpful in identifying high-risk patients. Obstructive sleep apnea syndrome (OSAS) leads to cardiovascular complications. Autonomic nervous system and baroreflex dysfunctions may play the main role in the development of cardiovascular diseases. In the present study we aimed to assess HRT parameters in OSAS patients with and without coronary artery disease (CAD) in comparison to control group...

A common problem in diagnostic medicine, when performing a diagnostic test, is to obtain an accurate discrimination between 'normal' cases and cases with disease, owing to the overlapping distributions of these populations. In clinical practice, it is exceedingly rare that a chosen cut point will achieve perfect discrimination between normal cases and those with disease, and one has to select the best compromise between sensitivity and specificity by comparing the diagnostic performance of different tests or diagnostic criteria available...

BACKGROUND: The aim of the study was to evaluate the contribution of relative lead strengths to exercise-induced ECG changes (ST depression) to predict the degree of myocardial ischemia as compared to the angiograms. This was accomplished by comparing the magnitude of ST depression to the ST/R ratio. Studies have shown that the diagnostic strength of a lead is directly related to the R wave amplitude and that sensitivity is significantly improved. METHODS: Three hundred patients, who underwent treadmill exercise testing and coronary angiography revealing significant coronary narrowing (> or = 70% luminal diameter narrowing), were studied, along with 150 patients clear of significant coronary artery disease (<70% luminar diameter narrowing)...

BACKGROUND: QT and corrected QT dispersion (QTD, QTcD) obtained by using the standard 12-lead ECG is a marker of nonhomogenous ventricular repolarization. QTD obtained from exercise ECG increases the diagnostic reliability of ST-segment changes. The aim of this study was to investigate the diagnostic accuracy of the QTD and QTcD obtained by a 12-lead ECG during the peak exercise in determining remote vessel disease in patients with healed Q-wave MI. METHODS: Eighty patients with healed Q-wave MI (mean age 54 +/- 8 years; 71 men, 9 women; 29 anterior; 51 inferior MI) who underwent exercise stress testing and coronary angiography were included in this study...

REVIEW
P Witek
Nowadays the cardiovascular diseases particularly ischaemic heart disease (IHD) are the most frequent causes of death in Poland. Some of patients with IHD are completely asymptomatic. These subjects are more susceptible to sudden coronary events due to lack of diagnosis and treatment. Cohn divided patients with asymptomatic ischaemia (AI) into three groups: completely asymptomatic, asymptomatic patients after myocardial infarction, patients with painful angina who have some ischaemic events asymptomatic. Some causes of AI are: increased pain threshold, increased beta-endorphin levels, impairment of pain pathways, smaller ischaemic regions in comparison with painful angina, psychological factors, transient platelet microaggregates...
