Transient myocardial ischemia during daily life in rest and exertional angina pectoris and comparison of effectiveness of metoprolol versus nifedipine.

The clinical characteristics of 65 patients with mixed angina were classified by means of (1) a questionnaire investigating the proportion of symptoms occurring at rest and on effort, (2) an exercise stress test, (3) 24-hour ambulatory Holter monitoring, and (4) coronary arteriography. According to the questionnaire, the proportion of effort-induced anginal episodes ranged from 1 to 99%. The ischemic threshold during exercise testing ranged from 110 x 10(2) to 350 x 10(2) mm Hg x beats/min.

Two-dimensional echocardiography in myocardial amyloidosis.

Two-dimensional echocardiography is the best means of identifying early cardiac amyloid infiltration and gauging its subsequent progression. The early asymptomatic phase is characterized on echocardiography by a mild-to-moderate increase in left ventricular and/or right ventricular wall thicknesses. The distinctive combination of low electrocardiography voltage and increase in left ventricular mass on the echocardiogram, both compatible with substantial amyloid infiltration, is valuable in diagnosis and appears to indicate the severity of the disease.

Quantitative texture analysis in two-dimensional echocardiography: application to the diagnosis of myocardial amyloidosis.

Qualitative and subjective analysis of two-dimensional echocardiographic images of the myocardial wall allows one to identify amyloid heart disease; the quantitative analysis of regional image texture might be an accurate method to differentiate normal from amyloid myocardial structures. To test this hypothesis, two-dimensional echocardiograms of nine normal subjects and six patients with histologically documented amyloid heart disease were evaluated. Quantitative texture measurements of the first order (mean gray level, skewness, kurtosis, energy and entropy) overlapped between the two groups.

[Diagnostic value of Q wave changes during the exercise test. Review of the literature and personal experience].

Unlabelled: To test if a low Q wave voltage and its faulty increase after exercise is an additional sign of myocardial ischemia, 64 pts with no previous myocardial infarction, bundle branch block or left ventricular hypertrophy were studied by a treadmill test and coronary angiography. Nineteen had single vessel disease (SVD), 21 double vessel disease (DVD), 4 triple vessel disease (TVD) and 20 normal coronary arteries. Sensitivity (SENS), specificity (SPEC) and predictive value (P) of Q wave changes have resulted as follows: 84%, 55%, 80.

Primary hyperparathyroidism and angina pectoris.

We report the case of a 50-year-old female suffering from angina pectoris with a positive exercise test and normal coronary arteriography. Nifedipine relieved the angina. Laboratory tests demonstrated hypercalcaemia and led to a diagnosis of parathyroid adenoma.

M-mode and two-dimensional echocardiography in congenital absence of the pericardium.

The M-mode and two-dimensional echocardiographic features of congenital absence of the pericardium are described in two cases that had been confirmed by clinical and radiological data. The M-mode echocardiogram showed right ventricular dilatation and abnormal systolic motion of the interventricular septum. Echo contrast studies with peripheral injection of saline solution revealed normal persistence of microbubbles in the right side of the heart.

Two-dimensional echocardiographic recognition of coronary artery disease in Kawasaki disease. A case report.

Two-dimensional echocardiography (2-DE) was used to demonstrate bilateral coronary artery disease in a 2-month-old child presenting with a mucocutaneous lymph node disease. The classic clinical and laboratory signs of this illness, now known as Kawasaki disease, were reviewed. Identification of the high risk patient prone to developing pericarditis and coronary perivasculitis with subsequent congestive heart failure or myocardial damage is essential for lowering morbidity and mortality rate.

[Precordial heart beats in myocardial infarct (clinical and electrocardiographic study in 40 cases)].

The precordial K1 to K6 cinetocardiograms in 40 patients with Myocardial Infarction (10 recent and 30 old) were studied. These were compared with the findings of the precordial palpetion, electrocardiograms, and the radiologic studies. In the recent infarcts, all the patients presented abnormal systolic "annoyances", 50% of which were palpable.
