Heart failure (HF) is a complex clinical syndrome resulting from any structural or functional cardiac disorder impairing the ability of the ventricles to fill with or eject blood. The approach to pharmacologic treatment has become a combined preventive and symptomatic management strategy. Ideally, treatment should be initiated in patients at risk, preventing disease progression. In patients who have progressed to symptomatic left ventricular dysfunction, certain therapies have been demonstrated to improve survival, decrease hospitalizations, and reduce symptoms. The mainstay therapies are angiotensin-converting enzyme (ACE) inhibitors and beta-blockers (bisoprolol, carvedilol, and metoprolol XL/CR), with diuretics to control fluid balance. In patients who cannot tolerate ACE inhibitors because of angioedema or severe cough, valsartan can be substituted. Valsartan should not be added in patients already taking an ACE inhibitor and a beta-blocker. Spironolactone is recommended in patients who have New York Heart Association (NYHA) class III to IV symptoms despite maximal therapies with ACE inhibitors, beta-blockers, diuretics, and digoxin. Low-dose digoxin, yielding a serum concentration <1 ng/mL can be added to improve symptoms and, possibly, mortality. The combination of hydralazine and isosorbide dinitrate might be useful in patients (especially in African Americans) who cannot tolerate ACE inhibitors or valsartan because of hypotension or renal dysfunction. Calcium antagonists, with the exception of amlodipine, oral or intravenous inotropes, and vasodilators, should be avoided in HF with reduced systolic function. Amiodarone should be used only if patients have a history of sudden death, or a history of ventricular fibrillation or sustained ventricular tachycardia, and should be used in conjunction with an implantable defibrillator [corrected]. Finally, anticoagulation is recommended only in patients who have concomitant atrial fibrillation or a previous history of cerebral or systemic emboli.

Cough is a complex defensive reflex whose purpose is protection of the respiratory tract. There are many nonrespiratory causes, particularly pulmonary congestion from heart disease. Coughs may be useful, useless, or harmful. Treatment based on etiology and type of cough requires only a few medications whose efficiency has been demonstrated. The meaning of cough as a symptom must be carefully determined before rational treatment can be planned. Recent researches on the physiology of the cough reflex, the bronchi, and the mechanisms of bronchial secretion have made it possible for a physician to plan a treatment program on a firm, scientific basis, rather than on tradition.

Bordetella bronchiseptica are small, pleomorphic Gram-negative coccobacilli which are commensal organisms in the upper respiratory tract of many wild and domestic animals ('kennel cough' in dogs). While it is common for health care providers to ask about exposure to ill family/friends, most do not routinely inquire about the health or immunization status of household pets. We report two cases of B. bronchiseptica pneumonia in lung transplant recipients [cystic fibrosis (CF); ages 10 and 15 yr; one male] who contracted B. bronchiseptica from pet dogs. We compared their course and outcome to four children (two CF, one congenital heart disease and one Duchenne's muscular dystrophy; four males, age range 6 months to 14 yr) with B. bronchiseptica cultured from the respiratory tract. Two of the four patients also acquired their illnesses from pet dogs and two from unknown sources. One lung transplant recipient expired from progressive respiratory failure. We conclude that B. bronchiseptica can cause serious infections in both immunosuppressed and immunocompetent children. We speculate that a detailed history of exposure to ill pets (particularly dogs), and the immunization status of all pets should be included in the routine evaluation of all pediatric transplant recipients.

There appear to be no infallible guides by which to differentiate between cardiac insufficiency and asthma as a cause of dyspnea, wheezing and coughing in elderly patients. Many of the symptoms of one condition are also symptoms of the other. Even the results of therapeutic trial cannot be relied upon to establish diagnosis, for drugs effective in treatment of heart disease may also help relieve asthma, and vice versa. Although there is no single factor that can be considered pathognomonic, there are certain symptoms and results of tests which are more strongly indicative of one condition than of the other. Careful evaluation of all factors, while it may not serve to establish unequivocal diagnosis, will provide a basis for judicious treatment of the patient.

The autopsy protocols of 560 patients were studied in order to detect the incidence of pulmonary embolism, 83 cases were found (15%). The clinical data was analyzed to establish the existence of differentiating points between subjects with pulmonary infarcts and those with embolism but without infarction. The necropsy findings were further scrutinized to determine the effect of the anatomic localization of the embolus upon the production of infarction. Pulmonary infarctions were present in 60% of the cases with pulmonary embolus. The presence of cardiac failure, valvular heart disease and left ventricular hypertrophy was significantly more frequent in patients with pulmonary infarcts. In subjects with or without infarction the age, sex and the presence of medical debilitating diseases, recent trauma, surgical interventions or postpartum, cardiac diseases, arteriosclerotic heart disease, clinical evidence of thrombophlebitis, prolonged bed rest and atrial fibriliation preceding the pulmonary embolism, did not evidenciate any significant difference. In the cases with infarction the pulmonary embolus was significantly more frequently located in the small and sublobar pulmonary artery branches, while when pulmonary infarction was not found the embolic process was more frequently located in the main, right or left pulmonary arteries; occlusion of the lobar arteries had approximately the same incidence in the two groups. The most common clinical signs of pulmonary thromboembolism were dyspnea, tachycardia, cough and shock. The presence of hyperthermia, cough, jaundice, bloody sputum, pleuritic pain, pleural friction rub and pleural effusion was significantly more frequent in those cases with pulmonary infarction; the last five features were present only in the presence of infarction. The electrocardiogram was strongly suggestive of pulmonary embolism in the 6% of all cases, while the chest X-ray in 30% of those with pulmonary infarct. The diagnosis was established antemortem in 40% of the cases with infarction and in 20% of the cases with embolus but without pulmonary infarction. In 23% adequate anticoagulant therapy was established.

The primary aim of this study was evaluation of the efficacy of telmisartan (angiotensin II receptor blocker- AT(1) blocker) on blood pressure in 10 patients with renal impairment in moderate or advanced stages of renal insufficiency and not dependent on haemodialysis. Its effect on proteinuria, renal function (represented by serum urea, creatinine, glomerular filtration), evaluation of overall therapy compliance in comparison with a previously prescribed angiotensin converting enzyme inhibitors (ACEI) were secondary aims. Considering the presence of left ventricle hypertrophy in all patients as a marker of hypertensive cardiopathy, the effect of telmisartan therapy on non-invasive cardiovascular parameters (ECG, echocardiography, and assessment of heart rate variability-HRV) was also evaluated. The study group involved 10 hypertensive patients (6 women, 4 men) with diabetic and non-diabetic renal impairment, proteinuria above 1 g/24 hours, hypertensive cardiopathy and intolerance of ACEI (cough). Telmisartan was added to their long-term antihypertensive combination therapy in a dose of 40 mg for the first 14 days, after which the dose increased to the maximal of 80 mg. The average initial daytime systolic blood pressure (SBP) was 149 +/- 19.7 mm Hg, average night-time SBP 145 +/- 23.0 mm Hg, average initial daytime diastolic BP (DBP) 90.6 +/- 2.5 mm Hg, night-time DBP 88.9 +/- 13.5 mm Hg. Average initial serum creatinine was 207.2 +/- 48.5 micromol/l, urea 15.1 +/- 4.4 mmol/l, GF 0.5 +/- 0.1 ml/s. Echocardiography revealed left ventricular (LV) hypertrophy with well preserved systolic and moderately impaired diastolic LV function. Also the HRV assessment revealed impaired neurovegetative (e.g. sympathovagal) balance. After 1 year of combination therapy with telmisartan, there was a clearly significant reduction in both SBP and DBP in both day and night-time (SBP daytime 149.6 vs.116.6 mm Hg, night-time 145.8 vs. 129.5 mm Hg; DBP daytime 90.6 vs. 83.5 mm Hg, night-time 88.9 vs. 79.3 mm Hg) and proteinuria (2.37 vs. 1.27 g/24 hour, p < 0.05). There were no significant changes in serum creatinine, urea values, and LV functions. On the other hand, further progression of the sympathovagal balance impairment was noted (continuing reduction of HRV in 9 from 10 patients), which can be described as the priority finding. The total compliance of telmisartan therapy was very good and without adverse clinical side effects. In conclusion - telmisartan reduces blood pressure and proteinuria safely and effectively in patients with various types of nephropathy in moderate or advanced stages of renal insufficiency.

Diffuse pulmonary ossification is a rare entity that presents with the formation of mature bone in the pulmonary parenchyma and is associated with diffuse and chronic lung disease, heart disease, or other system disorders. Diffuse pulmonary ossification is usually a postmortem finding by the pathologist. In the case we report, the diagnosis was established by open lung biopsy. The patient was a 79-year-old man with dyspnea, dry cough, and weight loss. He had been a smoker. A chest x-ray revealed reticulonodular bilateral pulmonary infiltrates. Computed tomography revealed interstitial disease predominantly in the septum with multiple cavitations that tended to form honeycomb patterns. Pleural thickening, retraction of the parenchyma, and bilateral fibrosis were also visible. A clinical diagnosis of interstitial fibrosis was established and the patient s course was unfavorable. An open lung biopsy was performed. The lung tissue specimens revealed zones with collapsed alveoli and others with emphysema, some of which produced secretion and erythrocytic extravasation. Interstitial vascular congestion was apparent; bronchioles presented mononuclear and some polymorphonuclear inflammatory infiltrates. Noteworthy was the presence of predominantly interstitial, multicentric foci of osseous trabeculae --some of which included adipose bone marrow. Diffuse pulmonary ossification is usually an incidental finding in autopsies of patients with a history of diffuse chronic pulmonary disease, but it is an unusual diagnosis in living patients. Diffuse pulmonary ossification is of no prognostic significance in pulmonary fibrosis. It is a marker of the chronicity and/or severity of the fibrosis.

Plastic bronchitis is a rare complication in which bronchial casts of lymphatic origin develop in the tracheobronchial tree and cause airway obstruction. The main feature is expectoration of bronchial casts. This condition usually occurs in the postoperative period after the Fontan operation for congenital heart disease. Treatment modalities include mucolytics and chest physiotherapy, and in the most severe cases bronchoscopy to remove the casts and aerosolized urokinase or r-TPA. We describe a 12-year-old boy with pulmonary atresia with intact ventricular septum and severely hypoplastic right ventricle who underwent a modified Fontan operation at the age of 7 years. At the age of 12 years the patient started to present frequent episodes of coughing, dyspnea, and desaturation followed by difficult emission of white bronchial casts. An extracardiac Fontan conversion was performed to improve hemodynamics and symptoms. During the postoperative period frequent episodes of airway obstruction required bronchoscopy and finally improved with administration of aerosolized urokinase.

The aim of the study was to use data from an electronic medical record system (EMR) to look for factors that would help us diagnose acute myocardial infarction (AMI) with the ultimate aim of using these factors in a decision support system for chest pain. We extracted 887 records from the electronic medical record system (EMR) in Selayang Hospital, Malaysia. We cleaned the data, extracted 69 possible variables and performed univariate and multivariate analysis. From the univariate analysis we find that 22 variables are significantly associated with a diagnosis of AMI. However, multiple logistic regression reveals that only 9 of these 22 variables are significantly related to a diagnosis of AMI. Race (Indian), male sex, sudden onset of persistent crushing pain, associated sweating and a history of diabetes mellitus are significant predictors of AMI. Pain that is relieved by other means and history of heart disease on treatment are important predictors of a diagnosis other than AMI. The degree of accuracy is high at 80.5%. There are 13 factors that are significant in the univariate analysis but are not among the nine significant factors in the multivariate analysis. These are location of pain, associated palpitations, nausea and vomiting; pain relieved by rest, pain aggravated by posture, cough, inspiration and exertion; age more than 40, being a smoker and abnormal chest wall and face examination. We believe that these findings can have important applications in the design of an intelligent decision support system for use in medical care as the predictive capability can be further refined with the use of intelligent computational techniques.

Atrial septal defect (ASD) is a common congenital heart disease (CHD) in humans, but considered relatively rare in veterinary medicine. However, modern echocardiographic and Doppler techniques currently offer a good view of the morphology of the interatrial septum, thus facilitating earlier detection of ASD in awake animals. In this context, we carried out a retrospective study of cases of recently diagnosed ASD in dogs and cats at the Cardiology Unit of Alfort (2001-2005) using echocardiography combined with colour Doppler mode. ASD was diagnosed in 156 animals and represented 37.7% of all canine and feline CHDs (n = 414). ASD was the most common CHD after mitral dysplasia in both species. Boxer and Domestic shorthair were the most common canine and feline breeds affected. Most defects (98.7%) were secundum-type ASD, without clinical signs in 73.7% of cases. The most common clinical signs included systolic murmur heard over the left heart base (20.2%), exercise intolerance (7.0%), syncope (5.3%), dyspnoea (2.6%) and cough (2.6%). Animals that presented a systolic heart murmur over the left base had a significantly larger ASD than others (P < 0.05). These data suggest that the incidence of ASD is higher than previously assumed. ASD should be suspected, for example, in instances of left basal systolic heart murmur, although its clinical and haemodynamic consequences are usually minor.
