CONTEXT AND OBJECTIVE: P2 hyperphonesis is considered to be a valuable finding in semiological diagnoses of pulmonary hypertension (PH). The aim here was to evaluate the accuracy of the pulmonary component of second heart sounds for predicting PH in patients with interstitial lung disease. DESIGN AND SETTING: Cross-sectional study at the University of Brasilia and Hospital de Base do Distrito Federal. METHODS: Heart sounds were acquired using an electronic stethoscope and were analyzed using phonocardiography. Clinical signs suggestive of PH, such as second heart sound (S2) in pulmonary area louder than in aortic area; P2 > A2 in pulmonary area and P2 present in mitral area, were compared with Doppler echocardiographic parameters suggestive of PH. Sensitivity (S), specificity (Sp) and positive (LR+) and negative (LR-) likelihood ratios were evaluated. RESULTS: There was no significant correlation between S2 or P2 amplitude and PASP (pulmonary artery systolic pressure) (P = 0.185 and 0.115; P= 0.13 and 0.34, respectively). Higher S2 in pulmonary area than in aortic area, compared with all the criteria suggestive of PH, showed S = 60%, Sp= 22%; LR+ = 0.7; LR- = 1.7; while P2> A2 showed S= 57%, Sp = 39%; LR+ = 0.9; LR- = 1.1; and P2 in mitral area showed: S= 68%, Sp = 41%; LR+ = 1.1; LR- = 0.7. All these signals together showed: S= 50%, Sp = 56%. CONCLUSIONS: The semiological signs indicative of PH presented low sensitivity and specificity levels for clinically diagnosing this comorbidity.

Harmful Effects

Thyrotoxic cardiomyopathy is potentially life threatening complications of thyrotoxicosis during pregnancy due to its harmful effects both on mother and fetus. We present a case of 32-year-old pregnant lady presented with non-productive cough, palpitation, restlessness, sweating and weakness after minimum exertion with a small swelling on the right side of her neck for three months. There was tachycardia with normal blood pressure, first and second heart sound were soft with pansystolic murmur on mitral and tricuspid area. After all laboratory investigations, she was diagnosed as dilated cardiomyopathy with moderate to severe pulmonary hypertension with toxic multi nodular goiter with 13 weeks of pregnancy.The thyrotoxic cardiomyopathy during pregnancy is rare due to difficulties in diagnosis. However, physicians should be aware of the risk posed by thyrotoxic cardiomyopathy during pregnancy. KYAMC Journal Vol. 11, No.-1, April 2020, Page 54-56

Blood Pressure Estimation

This paper aims to give a perspective on how the study of the heart sound relation with blood pressure has evolved. The use of heart sound as a surrogate of the BP has been used with more emphasis on the detection of pulmonary hypertension patients, considering the frequency content, amplitude, and split the second heart sound and its subcomponents, which arise following the closure of the corresponding heart valves. Estimation of BP using the analysis of heart sound is characterized by the simplicity of the equipment used to obtain data, which after analysis allows to achieve promising results that until now were only obtained with techniques far more complex and expensive equipment. The main objective of this article is to understand how heart sound analysis may be used to estimate blood pressure and which methods are employed to detect pulmonary hypertension.

Objective: development of a questionnaire for the early detection of pulmonary arterial hypertension (PAH), and its further introduction for a broad routine medical practice.Were identified clinical symptoms, allowing differentiate various forms of the disease (IPAH and PAH-CHD), because these forms of PAH most frequent in cardiology practice.Material and methods. The questionnaire includes 6 sections: clinical symptoms, physical examination, anamnestic information, diseases associated with pulmonary hypertension; signs of PAH according to electrocardiography, chest radiography, echocardiography. All sections of the questionnaire filled by physician. Was held a retrospective analysis of the clinical symptoms, physical examination, anamnestic information, methods of instrumental examination of 70 patients with IPAH in comparison with 29 patients with PAH-CHD and the control group - 48 patients with arterial hypertension (AH).Results. The leading complaints in patients with PAH are dyspnea (99%), palpitations (58%), fatigue (59%), syncope (21%), dry cough (28%), peripheral edema (38%). The physical signs of PAH include an accentuated pulmonary component of second heart sound (93%), cyanosis (40%). Most often, the development of pulmonary hypertension precipitated by stress, pregnancy, acute respiratory infections.Conclusion. According to the results we concluded that the developed questionnaire may be offered for wide use in routine clinical practice and recommended not only for screening patients with IPAH, but also with PAH-CHD.
