The most common form of lower airway disease (LAD) in dogs is chronic bronchitis, whereas in cats a syndrome resembling chronic bronchial asthma in humans is commonly reported. In most cases, the cause(s) of LAD remains unproven. The primary symptom of LAD in dogs and cats is chronic cough, although many cats are free of symptoms between episodes of acute, life-threatening bronchoconstriction. Diagnosis is based on a careful history, physical examination, and diagnostic tests designed to rule out other causes of cough and dyspnea such as pneumonia, heartworm infestation, and congestive heart failure. More sophisticated tests, such as bronchoscopy, flow volume loops, and radioisotope ventilation scans are available to define the extent of the disease process better. Glucocorticoids remain the mainstay of chronic therapy for most dogs and cats with LAD. Bronchodilators are indicated for most cats with symptoms of acute bronchoconstriction, whereas a smaller number of dogs may respond to bronchodilator administration and demonstrate an increase in exercise capacity and a decrease in cough frequency. LAD in dogs and cats is a progressive disorder, and prognosis is guarded. Nevertheless, with aggressive medical management many of these animals can live relatively symptom-free lives.

Cardiac hypertensive structural changes, catecholamine-related cardiomyopathy, and congestive heart failure (CHF) have been encountered in pheochromocytoma, as a result of prolonged exposure to high concentrations of endogenous catecholamines. A 34-year-old man presented with severe hypertension, cardiomegaly, and CHF, presumably as a result of continuous alpha-adrenergic intoxication with oxymetazoline hydrochloride, phenylephrine hydrochloride, and ephedrine hydrochloride, consumed in massive doses by an overuse of nasal decongestants and cough syrup (daily doses of 20, 100, and 300 mg, respectively). Coadministered chlorpromazine hydrochloride and trimeprazine tartrate may have also contributed to the clinical presentation through their anticholinergic and antihistaminic properties. The possibility of an overuse of these over-the-counter drugs should be considered in the differential diagnosis of hypertensive emergencies, especially with the simultaneous use of anticholinergic and antihistamine medications, beta-blocking agents, or monoamine oxidase inhibitors.

Captopril is widely used for congestive heart failure and arterial hypertension. Its main side effects are cough, neutropenia, and renal injury. Liver dysfunction has rarely been described. We present a 71-year-old man with an acute myocardial infarction who developed high fever and progressive disturbance of liver function tests, hepatocellular and cholestatic, after beginning captopril. When other, more likely causes for his condition were ruled out, captopril was discontinued and the fever and liver dysfunction then quickly resolved. We recommend periodic laboratory follow-up in patients treated with angiotensin-converting enzyme inhibitors.

Four hundred episodes of COPD among patients admitted to Chulalongkorn Hospital between 1982 and 1986 were analyzed. There were 193 males and 45 females with 325 and 75 episodes of admission, respectively; the average age on admission was 68.4 +/- 0.5 years. The most significant associated underlying factor was cigarette smoking in 94 per cent of the cases, with the patients smoking an average of 1.15 packs of cigarettes per day for 43 years. In our study, 26.8 per cent of the patients had a cough, with the average age at onset being 47.4 +/- 2.1 years. The most common clinical manifestation was dyspnea with 58.5, 35.2 and 0.5 per cent having dyspnea functional class II, III, IV and with the average age at onset being 61.1 +/- 0.7, 66.6 +/- 0.7 and 71.0 +/- 1.0 years, respectively. An important manifestation on admission was dyspnea functional class III and IV, which were present in of 89 per cent of the cases. The main precipitating factors which led to the patients' admission were upper respiratory tract infection, pneumonia, bronchospasms and congestive heart failure, which accounted for 48.0, 10.0, 8.5, 31.8 and 18.3 per cent of the cases, respectively. With regard to these complications, there were 16.5, 48.3, 31.1 and 12.5 per cent of the patients who suffered respiratory failure requiring assisted ventilation, corpulmonale, polycythemia and peptic ulcer, respectively. Arterial blood gas on admission revealed a pH level of 7.36 +/- 0.1, pCO2 of 53.3 +/- 23.7 torr, and PO2 of 54.2 +/- 19.9 torr.(ABSTRACT TRUNCATED AT 250 WORDS)

To date, there is no effective pharmacologic treatment for Chagas' cardioneuropathy, one of the most common causes of congestive heart failure and sudden death in the world. Fifty-eight adults with positive serology for Chagas' disease and abnormal autonomic nervous system tests participated in this placebo-controlled clinical trial with Cronassial (mixed gangliosides), 40 mg daily intramuscular injection for 4 or 8 weeks. We measured postural response (heart rate, systolic and diastolic arterial blood pressure changes in response to standing); heart rate changes induced by cough and hyperventilation reflex tests; dizziness on standing; number of stress-induced arrhythmias; and periodic acid-Schiff (PAS)-positive T-lymphocyte percentage in blood samples. Cronassial is safe and significantly improves systolic blood pressure (p = 0.050) and double product responses to postural stress (p = 0.028), hyperventilation heart rate response (p = 0.007), frequency of dizziness episodes (p less than 0.001), number of arrhythmias (p = 0.033), and percentage of PAS-positive T-lymphocyte counts (p less than 0.001) compared with placebo.

Since dry cough has recently been recognized as a side effect of angiotensin converting enzyme (ACE) inhibitors employed in the treatment of hypertension or congestive heart failure, the incidence of dry cough in elderly patients receiving ACE inhibitors was investigated. There were 237 out-patients on either captopril, enalapril, or delapril, in August and November 1989. Questionnaires concerning dry cough and smoking were completed by 184 patients. Patients either less than 50 years of age, or with chronic pulmonary disease were excluded. The remaining 168 patients, 63 males, 105 females, with a mean age of 73 years were analyzed for the incidence of a dry cough in relation to age, sex, smoking, and type of drugs. The overall incidence of a dry cough was 21/168 (12.5%), 7/63 (11.1%) for males and 14/105 (13.3%) for females, and was less frequent with advancing age; in the 51-60 age group 4/11 (36.4%), in the 61-70 age group 5/39 (12.8%), in the 71-80 age group 9/75 (12.0%), in the 81-90 age group 3/40 (7.5%), in the 91- age group 0/3 (0%). Enalapril showed significantly higher incidence of dry cough than captopril (16/93, 17.2% vs 7/88, 8.0%, p less than 0.05). Delapril showed an incidence 4/11, 36.4%, however, 9 out of the 11 patients who were given delapril had had a history of a dry cough with captopril or enalapril, and in 4 out of these 9 patients the dry cough disappeared by replacement of captopril or enalapril by delapril.(ABSTRACT TRUNCATED AT 250 WORDS)

Before the development of echocardiography, cardiac disease in the horse was diagnosed if a loud heart murmur (grade III-IV/VI or louder) and clinical signs of congestive heart failure (coughing, edema, venous distention, jugular pulsations) were detected on physical examination. Arrhythmias that persisted during and after exercise also indicated cardiac disease, which could be characterized electrocardiographically. Electrocardiography, thoracic radiography, angiography, cardiac catheterization, and oximetry could add only small pieces of information about the heart. M-mode echocardiography provided the first "window" with which to evaluate the heart and its intracardiac structures, albeit an ice-pick one-dimensional view. With M-mode echocardiography, the diameter of the aorta at the valves, the left ventricle, right ventricle, and left atrial appendage, as well as the thickness of the interventricular septum and left ventricular free wall, could be measured. Motion and thickness of the tricuspid, mitral, and aortic valves could be assessed, but only in a one-dimensional plane. Two-dimensional echocardiography provided an added dimension, resulting in visualization of all the intracardiac structures, aorta, and pulmonary artery. Two-dimensional echocardiography became the diagnostic technique of choice for the evaluation and characterization of congenital cardiac disease in critically ill neonates, as well as in adult horses. Two-dimensional echocardiography also improved the ability to diagnose valvular regurgitations, characterize valvular lesions (bacterial endocarditis, ruptured chorda tendineae), myocardial function (segmental wall motion abnormalities), atrial size, mass lesions (endocarditis, neoplasia, and thrombi), and pericardial effusion. Information about blood flow was obtained using contrast echocardiography but was limited to certain cardiac abnormalities (congenital cardiac defects and tricuspid regurgitation). This information about blood flow was limited to the detection of positive or negative contrast jets. Comprehensive information about blood flow was lacking until the application of Doppler echocardiography to equine cardiology. Pulsed-wave and color flow Doppler echocardiography resulted in precise localization of the abnormal blood flow and semiquantitation of the shunt flow or regurgitant jet. Color flow Doppler echocardiography sped up the localization and semiquantitation of the jet in many instances and provided some information about blood flow velocity in the enhanced and variance modes. The peak velocity of jets can be determined using continuous-wave Doppler echocardiography. This value then can be used to estimate pressure difference between cardiac chambers or to calculate cardiac output noninvasively if angles parallel to flow can be obtained. Thus, information about cardiac size, function, and blood flow can be combined to diagnose cardiac disease in horses and to formulate a prognosis for life and performance.

Angiotensin converting enzyme inhibitors (ACEI) are used widely in the treatment of both hypertension and congestive heart failure. Although usually well tolerated, these medications may produce side effects that may be encountered by the allergist, including cough, angioedema, and rhinitis symptoms. The severity of ACEI-induced cough may vary, and is associated with increased bronchial hyperreactivity in some (but not all) patients as judged by methacholine sensitivity. Angiotensin converting enzyme inhibitor-induced cough may have its onset from one day to 12 months after initiation of therapy, and is not dose dependent. Angioedema caused by ACEI is usually mild and clears with discontinuation of the drug, however cases requiring intubation and tracheostomy have been reported. The mechanism of ACEI-induced cough remains unclear, but could be in part due to accumulation of substances whose degradation may also be impeded by ACEI, such as substance P, bradykinins, and/or prostaglandins. Knowledge of the side effects produced by this class of medication may help patients avoid unnecessary, costly, and often invasive diagnostic evaluations.

Quinapril hydrochloride is a nonsulfhydryl angiotensin converting enzyme (ACE) inhibitor that has been extensively tested and found effective when administered once-a-day to hypertensive patients of both sexes and all degrees of hypertension and cardiac compromise, including those with left ventricular hypertrophy, with and without congestive heart failure. Observations with earlier ACE inhibitors led to reports that this class of drugs was relatively ineffective in older hypertensive patients. To ascertain the role of quinapril (greater than or equal to 10 mg/day) in older patients, its blood pressure-lowering effects in 1,175 hypertensive patients less than or equal to 65 years of age were compared with those in 304 patients greater than 65 years of age. An excellent response was observed in patients greater than 65 years of age with mild to moderate hypertension (diastolic BP, 95 to 105 mm Hg) and moderate to severe hypertension (diastolic BP, 106 to 115 mm Hg). The reductions in blood pressure achieved with quinapril were at least comparable to those obtained in the younger hypertensives, and were numerically (but not statistically) greater in the mild to moderate group (-14 mm Hg v-12 mm Hg). In addition, the percentage of patients who experienced adverse experiences was lower in the greater than 65 group than in the less than or equal to 65 group (15% v 19%). The main adverse experiences reported included dizziness, headache, cough, fatigue, and hypotension. These findings indicate that quinapril is at least as safe and effective in older hypertensives as in younger patients.

Angiotensin converting enzyme (ACE) inhibitors are becoming increasingly used in the treatment of hypertension. Although they are generally well tolerated, they have been implicated in the occurrence of certain side effects such as cough, hypotension and deterioration of renal function. These have been investigated prospectively during the development of perindopril. In a long term study in 632 hypertensive patients 6% of subjects stopped treatment prematurely because of adverse events and cough was the side effect most frequently responsible for treatment withdrawal (1.3%). A typical ACE inhibitor-induced cough was seen in a further 1.6% of patients. Symptomatic hypotension was rarely reported (0.2%), even in the elderly and patients with congestive heart failure. No clinically significant changes in plasma creatinine or potassium levels were seen during the long-term administration of perindopril in uncomplicated hypertensive patients. The overall safety profile of perindopril in clinical studies was favourable even in groups of more vulnerable patients. However the effect of long-term treatment with ACe inhibitors on cardiovascular morbidity and mortality is unknown.
