A 28-year-old woman presented to the emergency department for evaluation of acute chest pain. She lacked risk factors for coronary artery disease and her initial electrocardiogram (ECG) was nondiagnostic. Within 45 minutes of presentation she developed nausea, vomiting, restrosternal chest pain, and ECG changes compatible with an acute inferoposterior myocardial infarction. Emergent cardiac catheterization revealed three-vessel coronary artery ectasia and two-vessel occlusion. She underwent emergency coronary artery bypass grafting. Her myocardial ischemia was believed to have been induced by methergine, which she had been taking over the preceding 3 days. The etiology and pathophysiology of coronary artery ectasia, as well as the cardiovascular effects of methergine and a related drug, ergotamine, are discussed.

Coronary artery disease kills more women than all cancers combined, yet the clinical picture in women is different enough from men that the diagnosis can be missed or delayed. A cardiologist highlights these gender-based differences and explains why certain diagnostic tests are better than others at identifying CAD in women. Coronary artery disease (CAD) is the leading killer of women in the US. After menopause, mortality rates from CAD in women nearly equal those of men. Yet the clinical picture in women is different enough from that in men that it can obscure the correct diagnosis. Women are 10 years older than men, on average, when presenting with CAD, possibly due to delayed diagnosis or presentation. Differences in symptomatology between men and women are important to note. For example, other diseases, such as arthritis or osteoporosis, can obscure CAD symptoms. Further, compared with men, women's chest pain is more often associated with abdominal pain, dyspnea, nausea, and fatigue. More women than men with CAD have diabetes, hypertension, hypercholesterolemia, and a family history of CAD. Clinicians need to know how to assess the gender-specific pretest likelihood of CAD in women, starting with a careful review of the patient's chest pain history. Other risk factors, including smoking, abdominal obesity, and certain comorbidities, should be taken into consideration. The diagnostic accuracy of exercise testing is slightly lower for women than men. Certain diagnostic tests, particularly exercise echocardiography and exercise thallium/sestamibi testing, offer more prognostic information than traditional exercise electrocardiographic studies without imaging. Mortality associated with interventional procedures--such as angioplasty and coronary artery bypass grafting (CABG)--is slightly higher in women, although long-term survival rates are similar for both sexes. Detection of CAD at an earlier stage in women may result in earlier referrals for CABG, with the benefit of lower associated mortality rates.

Although angiotensin-converting enzyme inhibitors (ACEIs) are well-known causes of orofacial angioedema, angioedema from these agents involving the bowel is not often considered. We report a case of simultaneous onset of small bowel and orofacial angioedema due to captopril. A 61-year-old black man with hypertension, coronary artery disease, and congestive heart failure had been treated with captopril for 5 years. He had sudden swelling of the lips, face, and tongue, followed by nausea, emesis, abdominal pain, and diarrhea. Other medications included aspirin, indomethacin, allopurinol, colchicine, and nifedipine. Examination showed swelling of the tongue, buccal mucosa, and neck; he also had midabdominal tenderness but no respiratory distress. Laboratory data were normal. A C1-esterase inhibitor level was normal. An ileus pattern was present on abdominal x-ray film. Angioedema was diagnosed, and all signs and symptoms resolved in 24 hours after captopril was discontinued. Clinicians need to be vigilant for bowel involvement from ACEI angioedema.

A 45-year-old Mexican woman with a history of noninsulin dependent diabetes mellitus (NIDDM), hypertension, and coronary artery disease presented to the hospital after 2 months of intractable nausea, vomiting and diarrhea-all made worse by eating and drinking. She reported fever, chills, anorexia and a documented 50-pound weight loss during this period. She denied the signs and symptoms of melena, hematochezia, steatorrhea or constipation. She also reported left leg pain and decreased sensation and strength of her left leg compared to the right leg. She had been hospitalized 2 weeks prior to admission with the same symptoms and a diagnosis of viral gastroenteritis. She was also treated for H. pylori, but subsequent biopsy results were negative by Steiner stain.

The purpose of the study was to assess the safety, adverse effects and complications of the dobutamine stress echocardiography (ED). 582 patients without previous infarction were prospectively studied with ED. There were 196 female and 368 male, age varied from 27 to 74 years, mean 52. Dobutamine was given in stepwise increasing doses from 5 to 40 mcg/kg/min. Mean maximal dose achieved was 33 mcg/kg/min. Atropine was added in 253 (43%) cases. Significant coronary artery disease was present in 323 patients (53%). There were no death, no myocardial infarction or episodes of sustained ventricular tachycardia as a result of ED. The test was terminated when following conditions were revealed: target heart rate (28.9%), maximal established dose achieved (25.3%), left ventricular asynergy (19.6%), angina pectoris (10.8%), increase of systolic blood pressure above 220 mm Hg (2.6%), hypotension (7.6%), nonsustained ventricular tachycardia (1.7%). The most common non-cardiac side effects were skin tingling (19.8%), atypical chest pain(16.3%), palpitations (13.9%) and headache (7.9%). The most side effects were usually well tolerated, without the need for test cessation. The ED was terminated only in 4 (0.6%) patients because of non-cardiac side effects including nausea (0.3%) and headache (0.3%). We conclude that ED may be safely performed in routine clinical practice. Side effects were rare and usually minor. Most severe ischemic pain was relieved by test interruption and sublingual nitro-glycerine or short acting beta-blocker administration.

We report the details of a 40-year-old farmer, a cigarette smoker, who was admitted with general malaise, nausea, vomiting, upper abdominal pain, with ST-elevation on ECG suggestive of an acute anterolateral myocardial infarction. He was treated with nitrates, heparin, beta-blockade and angiotensin-converting enzyme (ACE) inhibitors. Because of the presence of some blood while vomiting no thrombolysis was given and abdominal echography was performed. This revealed a nodular mass at the right adrenal gland. Urinary catecholamines and abdominal magnetic resonance imaging confirmed the suspected diagnosis of pheochromocytoma. Before adrenectomy, a coronary angiography under alpha blocker therapy was performed, which demonstrated no significant coronary artery disease, although the patient showed ST-elevations on ECG. Pathological examination of the adrenal tumor was compatible with a diagnosis of pheochromocytoma. Postoperatively urinary catecholamines dropped dramatically, and the ECG normalised slowly over time. After 8 months the patient is still well. Blood pressure is well controlled with no antihypertensive drugs and exercise testing shows no evidence of myocardial ischaemia.

Apomorphine SL (TAP Holdings, Deerfield, IL) is a centrally acting treatment for erectile dysfunction (ED) that has been undergoing phase III trials. Over 3000 men have received apomorphine SL and over 75,000 doses have been taken. In the first three phase III parallel arm cross-over double-blind studies 854 patients were given a total of 8263 tablets of apomorphine SL in 2 and 4 mg doses. The patients were between 18 and 70 y old and outcome measures included per attempt rates of intercourse and erections firm enough for intercourse as well as psychometric instruments and partner responses. The majority (74.1%) had moderate and severe grades of ED on admission to the studies, 31% had hypertension, 16% had documented coronary artery disease, 16% had dyslipidemia and 16% had diabetes. Erections occurred rapidly (10-25 min) and in 54.4% of attempts at 4 mg (vs 33.8% placebo). A majority of the attempts at intercourse (50.6%) were successful at 4 mg in patients when recorded on a per-attempt basis. The most common but infrequent and mild side effect of nausea decreases with use. The phase III trials of apomorphine SL show that there is a clinically important restoration of erectile function from this new formulation of apomorphine. It has a rapid and safe effect through action in the central nervous system. Apomorphine SL brings a new choice to the management of ED that will further benefit the millions of couples affected.

In every year since 1984, cardiovascular disease has claimed the lives of more females than males. More than 450,000 women succumb to heart disease annually, and 250,000 die of coronary artery disease. Despite the proportions, most women believe they will die of breast cancer. The perception that heart disease is a man's disease and that women are more likely to die of breast cancer is alarming. Although women develop heart disease about 10 years later than men, they are likely to fare worse after a heart attack. The poorer outcomes are due, in part, to the failure to identify heart attack symptoms. Approximately 35% of heart attacks in women are believed to go unnoticed or unreported. However, because of increased age, women are more likely to have co-morbid diseases such as diabetes and hypertension. In women, not only is "tightness" or discomfort in the chest a warning sign, but in addition, nausea and dizziness are common indicators of myocardial ischemia. Other symptoms include breathlessness, perspiration, a sensation of fluttering in the heart, and fullness in the chest. In comparison to men, women are less likely to undergo tertiary care interventions such as cardiac catheterization, angioplasty, thrombolytic therapy, and bypass surgery; to participate in cardiac rehabilitation; and to return to work full-time after myocardial infarction. In the past, most research about treatments for heart disease focused on men, and gender differences have been ignored. Recent studies are enrolling enough women to test if there are differences between men and women in outcomes. One of the major areas of research relates to estrogen and hormonal replacement therapy to reduce the relative risk of heart attack and stroke. The Women's Health Initiative is a major NIH-sponsored trial that addresses the issue of primary prevention of cardiac disease by hormonal replacement therapy. The results will be available in 2004. The Heart Estrogen/Progestin Replacement Study (HERS), disappointingly, did not show a significant reduction of coronary events in women taking hormonal replacement therapy, nor did the Estrogen Replacement and Atherosclerosis (ERA) trial of 309 postmenopausal women who underwent coronary angiography. New insight into the role of vitamins, phytoestrogens and other natural sources, and selective estrogen receptor modulators may provide other options for management. Until then, modification of risk factors and healthy life style choices are recommended for reducing the risk of cardiac disease. In fact, the key to a healthy heart in the year 2000 appears closely tied to life style choices. Prevention of disease is the key, and current recommendations are simply to stop smoking, or do not start; treat and control blood pressure >140/90 mm Hg; manage elevated lipids by diet, exercise, and cholesterol-lowering medications (if necessary); treat diabetes; lose weight so that BMI is <25; walk for 20-30 minutes at least three times a week; and take an aspirin tablet daily.

The central nervous system has the capacity to enhance the activity of dysfunctional penile tissue in men with erectile dysfunction (ED). Phase III clinical trials have been conducted using Apomorphine SL (TAP Pharmaceuticals, Deerfield, IL) as a centrally acting treatment for ED. Apomorphine SL has been administered to over 3,000 men in over 75,000 doses. In three phase III crossover double blind studies 854 patients were given a total of 8,263 tablets of apomorphine SL in 2 and 4 mg doses. The patients were between 18 and 70 years old and had multiple co-morbid conditions. Outcome measures included intercourse rates and erection rates on a per attempt basis as well as psychometric instruments and partner response evaluations. The results show that 74.1% of patients had moderate or severe grades of ED on inclusion into the studies, 31% had hypertension, 16% had documented coronary artery disease, 16% had dyslipidemia, and 16% had diabetes. Erections occurred rapidly (10-25 min). In 54.4% of attempts at 4 mg (vs 33.8% placebo, P < 0.001) erections suitable for intercourse were documented. A majority of the attempts at intercourse (50.6%, P < 0.001) were successful at 4 mg a doubling of baseline rates. Mild nausea was the most common but infrequent side effect and the rare occurrence of syncope was the most significant. No cardiac deaths were attributed. It is concluded that the clinical trials of apomorphine SL demonstrate a safe and significant rate of restoration of erectile function by means of a central mode of action. Efficacy has been shown in men with cardiovascular disease and severe grades of ED.

Previous studies showed that increased QT dispersion (QTd) has been observed during episodes of myocardial ischemia or infarction and identify the patients at risk of arrhythmia or sudden death. The objective of this study is to investigate the relationship between coronary artery disease and QTd during the Valsalva maneuver. The study population included 85 subjects (21 with normal coronary arteries, 35 with stable angina pectoris, and 29 with unstable angina pectoris). Twelve-lead surface ECGs were recorded at 50-mm/sec paper speeds and were obtained before the Valsalva maneuver and during the strain phase. The results indicate a significant difference in mean time increase between the control group and the group with stable angina pectoris (mean difference = 16.10 milliseconds, p<0.000), and between the control group and the group with unstable angina pectoris (mean difference = 35.26 milliseconds, p<0.000). The mean difference in time between these groups was also compared (mean difference = 19.17 milliseconds), and was statistically significant (p<0.000). There are some conditions like constipation, severe coughing spells, nausea, vomiting, and carrying or lifting heavy objects that increase intrathoracic pressure and may increase QT dispersion. Therefore, all these conditions should be treated appropriately and carrying or lifting heavy objects is forbidden, especially in patients with coronary artery disease.
