Fontana, F., P. Bernardi, E. Merlo Pich, S. Boschi, R. De Iasio and S. Spampinato. Endogenous opioid peptides and mental stress in congestive heart failure patients. Peptides 19(1) 21-26, 1998.-Two groups of patients with acute congestive heart failure (CHF), New York Heart Association class III, presenting elevated plasma values of β-endorphin, norepinephrine, atrial natriuretic factor (ANF) and...
At peak exercise, plasma endothelin-1 concentration increases in patients with effort angina as well as thallium-201 radionuclide perfusion defects; the opposite occurs in patients with normal scans and in healthy volunteers. It is concluded that exercise-induced ischemia correlates with enhanced endothelin-1 production.
Circulating levels of atrial natriuretic factor (ANF), the education of myocardial contractility (evaluated by ejection fraction, EF) and different pain intensity were assessed in patients with uncomplicated acute myocardial infarction (AMI). We investigated the relationships between ANF, or EF, and pain intensity by identifying appropriate statistical methods and introducing a procedure for pain...
Fontana, F., P. Bernardi, E. Merlo Pich, S. Boschi, R. De Iasio, S. Spampinato and G. Grossi. Opioid peptide modulation of circulatory and endocrine response to mental stress in humans. Peptides 18(2) 169–175, 1997.—Healthy subjects were classified according to their percent increase in systolic blood pressure (SBP) after mental arithmetic test (MAT) as low (ΔSBP 9.3–15.1%, n = 15) and high (ΔSBP...
To investigate the relationship between plasma atrial natriuretic factor (ANF) levels, impaired myocardial contractility and pain intensity in acute myocardial infarction (AMI) we introduced a procedure estimating the pain component not influenced by the individual emotional reaction to stress, i.e., the original pain sensation. We deduced this pain component during AMI by correcting the personal...
