The present study identified factors that distinguish early responders (i.e., requested medical assistance < 60 minutes after the onset of acute myocardial infarction [AMI] symptoms) from late responders (i.e., request made > or = 60 minutes after symptom onset). A questionnaire developed to assess demographic characteristics, contextual factors, antecedents to symptom onset, and behavioral, affective, and cognitive responses was administered in the hospital to 501 patients with documented AMI. Patients who believed that their symptoms were cardiac in nature were more likely to be early responders, whereas patients who attributed their symptoms to indigestion, muscle pain, fatigue, or another cause responded later (p < 0.0009). Early responders believed their symptoms to be more serious (p < 0.0001), felt more comfortable seeking medical assistance (p < 0.0001), were more anxious or upset when they first noticed symptoms (p = 0.0118), and perceived that they had less control of their symptoms (p < 0.0001) than late responders. A stepwise multiple regression analysis further suggested that unmarried patients responded significantly later than married patients, and patients who first experienced their symptoms at work responded significantly later than those who first experienced their symptoms outside of the home but not at work. These results suggest that situational and psychological variables are important determinants of lengthy decision delays in responding to symptoms of AMI.

Erectile dysfunction (ED) in men is amenable to correction with Viagra in a majority of patients. The accumulated experience of prescribing Viagra across the broad continuum of men suffering from ED is sufficient for a meaningful assessment of the safety of Viagra in clinical practice. The use of Viagra necessitates caution in cardiac failure and when used within six months of acute myocardial infarction and stroke. It is inadvisable in patients with unstable angina pectoris. The co-administration of Viagra with organic nitrates, for example, glyceryl trinitrate or isosorbide dinitrate, is unsafe. The relative contraindications to Viagra in cardiovascular disease are uncontrolled hypertension and impaired cardiac reserve. With respect to interactions with other drugs, the potential influence on the metabolism of Viagra by medications that affect the cytochrome-P-450 system does not translate into clinical effects. The vasodilatory properties of sildenafil citrate are largely responsible for unwanted effects. The most common side effects are headache, flushing (due to vasodilation), and dyspepsia (due to relaxation of the smooth muscle of the gastroesophageal sphincter with reflux). In the recommended single-dose range (25-100 mg), the use of Viagra for erectile dysfunction, in the absence of contraindications, is extremely safe provided the drug is taken under proper conditions.

Evidence has begun to accumulate that suggests there may be gender differences in the presenting symptoms of acute coronary syndromes (ACS). Identification of gender differences has implications for both health care providers and the general public. Women should be instructed as to the symptoms expected with ACS on the basis of evidence obtained from studies that include both sexes. Twelve studies that identified symptoms of ACS for both women and men were identified through a review of the literature. In several of the studies, which included all types of ACS, women had significantly more back and jaw pain, nausea and/or vomiting, dyspnea, indigestion, and palpitations. In a number of the studies, which solely sampled patients with acute myocardial infarction, women demonstrated more back, jaw, and neck pain; nausea and/or vomiting; dyspnea; palpitations; indigestion; dizziness; fatigue; loss of appetite; and syncope. Men reported more chest pain and diaphoresis in the myocardial infarction sample. Results of these studies showed that women and men experienced the same symptoms with ACS. However, in some studies there were gender differences in the proportion of symptoms. Given the current state of the science, definitive conclusions regarding gender differences in the symptoms of ACS cannot be drawn. Further study is urgently needed to clarify and expand on these findings.
