On 33 patients with mitralic heart disease (III and IV class N.Y.H.A.) we have carried out polimechanical investigations (ecg, fcg, x-ray examination, external heart impulse record) and the following parameters was determined: 1) interval Q-I sound; 2) interval II sound-OS; 3) Wells's index; 4) Q-I sound/II sound-OS ratio; 5) duration of electromechanical systole of right ventricle; 6) duration of external heart impulse; 7) relative amplitude of E and E1 as percentage of amplitude from E point to nadir point; 8) relaxation isovolumetric time of right ventricle; 9) medium value of pulmonary capillary pressure, total pulmonary resistances, and area of mitral valve. The results demonstrate that there is a correlation between these parameters and the pulmonary blood pressure, whose value is possible to determine as well as haemodynamic investigation. The data indicate validity of non invasive techniques in detecting pulmonary hypertension in mitralic valve diseases.

During the 1991 Gulf War, the Iraqi army set Kuwait oil wells on fire. Wells and some oil refineries were burned, resulting in Kuwait and the surrounding Gulf region being exposed to toxic gases. The oil fires reached their peak in February 1991. On March 7, the fires in some fields were still burning at peak strength. Sulfur dioxide, particulates, carbon monoxide, and nitrogen oxides were emitted into the atmosphere. All of these substances can cause adverse health effects, which vary according to concentration and duration of exposure. A survey conducted in Kuwait clinics and emergency rooms showed an increase in upper respiratory irritation consistent with environmental air sampling results, indicating occasional high levels of particulates. Patient visits related to gastrointestinal illness, heart disease, psychiatric illness, chronic bronchitis and emphysema, and bronchiectasis increased during the period following the burning of the oil wells. There was no documented evidence of an increase in visits for acute upper and lower respiratory infections or asthma. Public health workers must recognize the high priority of collecting long-term health data and developing public health systems to assess those data.

The global healthcare burden of venous thromboembolism (VTE) and associated comorbidities (e.g., obesity, heart disease and cancer) is significant. Physical activity-especially cardiovascular exercise-is popularly acclaimed for gold-standard prevention. Paradoxically, intensive training can expose athletes to several potentially thrombogenic risk factors (e.g., heat stress, dehydration, blood vessel injury and inflammation). However, awareness regarding the risk of VTE in physically active people is generally lacking. Given that the overall incidence of asymptomatic and/or occult blood clots that resolve spontaneously is uncharted, and because symptoms and sequelae are not always 'textbook', triage evaluation and diagnosis of VTE at large can be challenging. Front-line clinical evaluations, including the major Wells scoring criteria, are (versus the total number of possible factors and diagnoses) comparably reductionist, and the point at which a minor risk might be considered significant in one person-but not in another-is subjective. Considering the popular associations between VTE and inactivity, athletes might be at greater risk of a missed diagnosis quite simply because their cardiovascular conditioning presents as the polar opposite to standard assessment criteria. Undoubtedly, risk factors for VTE associated with exercise are not unique to cardiovascular training or athletes, but the extent to which they might increase the chances of blood clot precipitation in certain participants warrants attention. A multi-agency approach, including research to inform mainstream understanding and awareness about risk factors for VTE in patient groups across age, comorbidity and activity spectra, is required. In this article, the potential for pre-participatory thrombophilia screening, haemostatic monitoring and personalized prophylactic guidelines is discussed.

Dyspnea represents 3-4 % of consultations at primary care medicine (general medicine, emergency medicine) and is found in 14 % of the interviewed general population. It is defined as an abnormal and uncomfortable breathing and can be classified according to the mode of appearance, the breathing pattern or the rhythm. Different classifications are used to specify the severity of the situation: visual analog scale, functional classification of the New York Heart Association, dyspnea modified scale from the Medical Research Council, ... Rare among young people, dyspnea often hides asthma; more prevalent among seniors, it is often secondary to chronic lung or heart disease. The rational approach is the same in general medicine and in the emergency room. The management starts with an assessment of the severity of the patient's clinical situation, via the early warning score. The critical patient requires to be managed according to the progressive and cyclical ABCDE approach. For non-critical patients, a traditional approach and a reasoned method are needed. In patients suffering from chronic obstructive pulmonary disease (COPD), the use of the Anthonissen criteria allows to orient toward a pulmonary superinfection or another cause of worsening dyspnea (cardiac, ...). In case of suspected pulmonary embolism, the Geneva score and the modified Wells score help to separate low, intermediate or high probability cases of pulmonary embolism. D-dimers have a very good negative predictive value in the low and middle risk group and pulmonary CT angiography applies only to a smaller group of dyspnoeic patients with a high probability of pulmonary embolism. Echocardiography has a prominent role to assess the LV systolic function, the search for pulmonary artery hypertension, the vascular filling state, etc. We speak of psychogenic dyspnea after having excluded the potentially serious pathologies.
