Several investigators demonstrated that severe reduction of colloid osmotic pressure (COP) predicts a fatal outcome in patients with cardiopulmonary failure. To evaluate the clinical significance of COP in relation to pulmonary edema, we studied 117 patients with unstable angina admitted in the hospital within 24 h after the chest pain. The mean COP of all 117 patients was 24.8 +/- 3.7 mmHg. COP was significantly lower in patients with pulmonary edema, according to the chest x-ray findings, compared with the patients without it. Among 26 patients with emergency coronary arteriography, a fairly good correlation was observed between coronary jeopardy score and COP (r = -0.57, p less than 0.005). Furthermore, COP in patients who survived 26 months after the hospital discharge was significantly higher than that of the nonsurvivors. Thus, measurement of COP is advised for monitoring patients with unstable angina.

Ten patients, who were admitted to the Intensive Coronary Care Unit during a one year period with symptomatic bradycardia while on combination therapy with oral diltiazem and beta-blocker agents, are described. The important features of this adverse reaction to drug combination were that it appeared mainly in a relatively elderly age group and with presenting symptoms of lethargy, dizziness, syncope, chest pain, and (in one patient with poor left ventricular function) pulmonary edema. It was not dose dependent and occurred even in very low doses of each drug. Electrophysiologic abnormalities were localized to the sinus node in all 10 patients and the primary rhythm disorders were junctional escape rhythm, sinus bradycardia, and sinus pause. These rhythm abnormalities resolved within 24 h following withdrawal of the offending drugs. Temporary pacemaker insertion was necessary in four patients. The duration of drug combination used before the acute episode range from within hours to up to 2 years. In conclusion, although combination diltiazem/beta blocker therapy is very effective in ischemic syndrome, caution is advised when this combination is used especially in the elderly or in patients with left ventricular dysfunction or antecedent sinoatrial or atrioventricular conduction abnormality.

Age is one of the important prognostic factors for acute myocardial infarction. This study was performed to clarify the clinical characteristics and outcome of acute myocardial infarction in Chinese geriatric patients. The study subjects included 742 patients, divided by age into 2 groups: Group A greater than or equal to 65 years, 321 cases; and Group B less than 65 years, 421 cases. The following characteristics were compared between these 2 groups: sex composition; presence of chest pain, heart failure or shock at presentation; cardiac functional status; occurrence of various complications, and follow-up data. Males were less prominent in the older group: 229 patients (71.3%) in Group A, and 371 patients (88.1%) in Group B. At onset, the older patients presented with less chest pain (72% vs 86.5%) and more heart failure (35.2% vs 20.2%), but the occurrence of shock was similar (5.9% vs 4.5%, for Groups A and B, respectively). During hospitalization, more patients in Group A showed impaired cardiac function, as evidenced by a higher percentage of patients identified as in Killip class III or IV (35.4% vs 21.1%). Concerning complications, the older group showed a higher incidence of hypotension, low cardiac output, lung edema, frequent premature ventricular beats, atrial flutter and/or fibrillation, complete heart block and intraventricular conduction defects, but ventricular septal defects, ventricular tachycardia and ventricular fibrillation did not show any difference in occurrence. Life table analysis showed that the survival rate was significantly lower for Group A during the follow-up period of 5 years.(ABSTRACT TRUNCATED AT 250 WORDS)

The safety of prehospital pharmacologic therapy has not been well studied. The authors evaluated field use of morphine sulfate (MS) in San Francisco County over a 6-month period. Paramedics assessed patients for ischemic chest pain (ICP) and/or pulmonary edema (PE), made base hospital contact, and administered 2- to 4-mg doses of intravenous morphine according to treatment protocols. Clinical assessments and patient responses to therapy were recorded by both field paramedics and emergency department (ED) physicians. Safety was evaluated by determining the (1) accuracy of paramedic field assessment, (2) appropriateness of field administration of MS, and (3) therapeutic complications. During the study period, paramedics administered MS to 84 patients. In 69 cases paramedic assessment of either ICP and/or PE corresponded to ED physician diagnosis. In five cases paramedics correctly recognized ICP but missed physical findings of PE. In this group the paramedics' assessment was considered inaccurate but the judgement to give MS was considered appropriate. In the remaining 10 cases paramedics identified ICP or PE but the ED physician diagnosed a different condition. These assessments were considered inaccurate and the management inappropriate. Therefore, overall paramedic accuracy was 77% (true rate 73% to 82%, 95% confidence interval); appropriateness of therapy was 88% (true rate 85% to 92%, 95% confidence interval); and the overall complication rate was 6% (true rate 2% to 12%, 95% confidence interval). Complications of respiratory depression or hypotension occurred in only one of the cases in which MS was inappropriately administered.(ABSTRACT TRUNCATED AT 250 WORDS)

One hundred nineteen patients admitted to the coronary care unit with pulmonary edema were retrospectively reviewed to identify the demographic characteristics and underlying cardiac disorders of this population. The patients with pulmonary edema were compared with 119 patients admitted to the coronary care unit with chest pain. Cardiac catheterization in 71 patients with pulmonary edema and 93 with chest pain showed left main and 3-vessel coronary artery diseases to be equally common in both groups, although anginal pain was infrequent in patients with pulmonary edema (n = 28, 24%). Left ventricular function was reduced in the patients with pulmonary edema compared with those with chest pain (mean ejection fraction 42 vs 59%; p less than 0.001). More patients with pulmonary edema were black, and had diabetes and preexisting hypertension than those with chest pain. The results of cardiac catheterization were the same for black and white patients with pulmonary edema. In conclusion, patients with pulmonary edema have a high incidence of cardiac disease, and pulmonary edema may be 1 manifestation of silent myocardial ischemia. Important demographic differences exist between patients admitted with pulmonary edema and those who present with chest pain.

Leiomyosarcoma of the esophagus is a rare neoplasm. We reported a very rare case of esophageal leiomyosarcoma associated with pulmonary edema by the compression of the left atrium. A 67-year-old man was admitted with a 3-month history of chest pain, exertional dyspnea and dysphagia. Chest X-ray computed tomography showed posterior mediastinal tumor. Esophageogastroscopy and fiberoptic bronchofiberscopy showed no direct invasion of the tumor. By echocardiography, the left atrium was found to be compressed by the tumor and pulmonary hypertension (58/25 mmHg) and increased pulmonary wedge pressure (25 mmHg) was present. Open biopsy specimen demonstrated elongated cells suggestive of sarcoma. At autopsy, the tumor was confirmed to be leiomyosarcoma and to be originated from the lower esophagus.

E-D is a powerful technique that can provide invaluable information in the acutely ill cardiac patient. It can help in the early diagnosis of conditions causing acute chest pain such as AMI and aortic dissection. E-D can help diagnose the causes of underlying hemodynamic instability such as hypotension and pulmonary edema, and it can help determine the initial management strategy. In this regard, E-D can replace Swan-Ganz catheterization in most patients. In patients with AMI who may appear to be hemodynamically stable, it can provide information regarding the following: size of risk area; status of the regions of the myocardium remote from the infarcted zone; effect of reperfusion therapy on regional myocardial function; presence or absence of nonsurgical complications such as ischemic mitral regurgitation, LV thrombus, or aneurysm; and patients at risk for immediate or late cardiac events. It is likely that as the newer generation of cardiologists becomes adequately trained in E-D, this technique will find routine use in every critical care unit.

An obese woman with a one-year history of episodic nocturnal chest pain was admitted because of shock and pulmonary edema. A clinical diagnosis of acute myocardial infarction and cardiogenic shock was made. She was ventilated and successfully resuscitated. Subsequent investigations showed no evidence of cardiac dysfunction or coronary disease, but sleep study confirmed the diagnosis of obstructive sleep apnea syndrome (OSAS). We suggest that the nocturnal angina and heart failure in this patient might have resulted from extreme hypoxemia produced by OSAS. This case raised the possibility that the high cardiovascular mortality rate reported in OSAS might not necessarily relate to underlying coronary artery disease. Further investigations are required to delineate the true incidence of coronary disease in patients with OSAS.

Autonomic neural impulses that accompany discharges during a seizure can cause a variety of cardiac manifestations, including cardiac arrhythmias, sudden death, anginal chest pain, neurogenic pulmonary edema, and symptoms of pheochromocytoma. Either generalized or focal seizures may generate such signs and symptoms. A better appreciation of cardiac problems caused by epilepsy is helpful in preventing misdiagnosis, because the clinical picture in such a patient may be confusing.

A 37-year-old woman had undergone aortic valve replacement with Smeloff-Cutter prosthetic valve in 1967. She visited our hospital because of dyspnea and chest pain about 22 years after the operation. Severe aortic regurgitant murmur was audible and a chest X-ray demonstrated lung edema. A diagnosis was made of acute left heart failure due to prosthetic valve dysfunction, and emergency operation was performed. The Silastic ball was severely deformed and shrunken. Therefore, the ball was easily put off outside the cage. A St. Jude medical prosthetic valve was implanted. The postoperative course was uneventful.
