2. 1. Myocardial Perfusion and Function: Comparative assessment by ECG, SPECT and MRI

   Author : Eva Persson; Lund Klinisk fysiologi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; tomografi; medicinsk instrumentering; Physiology; radiologi; radiology; tomography; medical instrumentation; Klinisk fysiologi; Clinical physics; ST-segment deviation ; myocardial ischemia ; myocardial perfusion ; MRI; CMR; MPS; ECG; SPECT; Fysiologi; Cardiovascular system; myocardial function ; Kardiovaskulära systemet;

   Abstract : Evaluation of myocardial perfusion and function is important in management of patients with suspected or known coronary artery disease. This thesis focuses on the use of common diagnostic methods, myocardial perfusion single-photon emission computed tomography (MPS) and electrocardiography (ECG), to enhance and validate the diagnostic information.

4. 2. Unstable post-infarction ischemia : identification and risk stratification with special emphasis on noninvasive methods

   Author : Miguel Quintana; Karolinska Institutet; Karolinska Institutet; []
   Keywords : myocardial infarction; myocardial ischemia; prognosis; exercise test; stress echocardiogaphy. ambulatoryelectrocardiography; heart rate variability.Stockholm 1996;

   Abstract : Although in-hospital mortality after acute myocardial infarction has decreased, long-term mortality is still high. This study tested the prognostic value of detecting residual myocardial ischemia by different techniques in 74 patients recovering from an acute myocardial infarction. READ MORE

5. 3. Prognostic implications of exercise induced and ambulatory ischemia in patients with stable angina pectoris

   Author : Lennart Forslund; Karolinska Institutet; Karolinska Institutet; []
   Keywords : angina pectoris; exercise testing; ambulatory ECG; signs of ischemia; heart rate variability; catecholamines; metoprolol; verapamil; prognosis;

   Abstract : Results from exercise testing and ambulatory ECG registration were studied in 809 patients with stable angina pectoris; special attention was paid to signs of ischemia during both tests. Autonomic nervous system activity was investigated by measurements of heart rate variability (HRV) and catecholamines in plasma and urine. READ MORE

6. 4. Blood pressure, blood pressure variability and myocardial ischemia : studies in patients with peripheral arterial disease and matched control subjects

   Author : Per Svensson; Karolinska Institutet; Karolinska Institutet; []
   Keywords : Peripheral vascular diseases; hypertension drug therapy; ambulatory blood pressure monitoring; coronary artery disease; ambulatory electrocardiography; SPECT; NT-proBNP;

   Abstract : Background: Patients presenting with peripheral arterial disease (PAD) often have concomitant coronary artery disease (CAD), which is frequently asymptomatic. Ambulatory blood pressure (ABP) monitoring improves risk stratification in hypertensive patients beyond that offered by office BP(OBP) measurements. READ MORE

7. 5. Beat-to-beat variability of QRS amplitude and heart rate in ischemic heart disease : diagnostic potentials

   Author : Inger Hagerman; Karolinska Institutet; Karolinska Institutet; []
   Keywords : autonomic blockade; beat-to-beat variability; chaos; coronary arterydisease; correlation dimension; dobutamine; ECG; electrical heterogeneity; fractal dimension; heart rate variability; Lyapunov exponent; nonlinear; QRSvariance; surrogate data;

   Abstract : The diagnostic potential of beat-to-beat QRS amplitude variability in patients with coronary artery disease (CAD) was evaluated with variance ECG and compared to exercise stress test and myocardial scintigraphy (SPECT). Two high prevalence populations of 199 and 166 patients each were investigated. READ MORE
