Early Diagnostics and Mathematical Prediction Models Remodeling of the Heart at Patients With Atopic Bronchial Asthma

The research purpose: to study features of clinical process of a coronary heart disease when it combines with a bronchial asthma.The materials and methods: 180 people were included in the research, 90 of them suffer from both CHD and BA (the first group), and also 90 people have only CHD without BA (the second group). The examination included complaint collection process, studying medical history, medical examination, percussion, auscultation, blood pressure measurement with the Korotkov’s method twice a day (in the morning and in the evening), heart rate measurement, 24-hour Holter ECG monitoring, echodoplercardiography. Besides, standard laboratory biochemical testing, including total cholesterol and lowdensity lipoprotein cholesterol, were made with the enzymatic colorimetric method.The results. Dyspnoea is the main complaint among 86 patients with both CHD and asthma, humans have (95,5%), moreover, dyspnoea combines with heartbeating in 73,8%, and is accompanied by angina pectoris only in 20%. There is a significant difference between systolic and diastolic blood pressure (р=0,001) that becomes higher if CHD combines with asthma. The signs of left ventricular and interventricular septum hypertrophy were discovered in the first group, these signs statistically significantly differ from the ones in the second group. The medium pulmonary arterial pressure is significantly higher in the combined group than in the group with only CHD (р=0,001). It is revealed with 24-hour Holter ECG monitoring that cases of myocardial ischemia are more frequent in the group which consists of patients with CHD. Besides, duration of ischemic depression per day is longer in this group too. It might be that if patients have both CHD and asthma they do not reach an ischemic threshold because of dyspnoea due to a respiratory failure.The conclusion. According to our findings bronchial asthma occurs among patients with coronary heart disease in 16.6% of cases. It is a distinctive feature of a bronchial asthma associated with coronary heart disease, that a patient often complaints to dyspnea (cardiopulmonary) and palpitation, increase in arterial blood pressure and heart rate, which appropriately indicates the activation of rennin-angiotensin-aldosteron and sympathicoadrenal systems. It requires the inclusion of appropriate drug groups in the treatment of patients.

Background: Uncontrolled asthma (BA) can be complicated by cardiac conduction disturbances and arrhythmias. It is typical mainly for adult asthmatics patients. In asthmatics children the effect of bronchoconstriction on cardiac conduction, including the supraventricular component of the ECG, is currently under discussion. The objective of the research is to analyze ECG parameters of the atrial complex and atrioventricular conduction and to assess their relationship with spirometric indicators in children with BA. Methods: Hundred three patients with BA from the age of 6-17 years were examined. The spirometric parameters were evaluated, including the Tiffeneau index (TI): FEV1/FVC (%), according to the level of which the patient groups were distinguished. Group 1 (G1): with TI more than 85%, (n = 15); Group 2 (G2): with TI from 85 to 75%, (n = 40); Group 3 (G3): with TI <75%, (n = 48). The ECG parameters that characterize supraventricular conduction, including the PQ interval (sec) and the sPQ segment (sec), were analyzed. We had calculated relative PQ (rPQ) by the formula rPQ=PQ/PQmed, where PQ is the patient's PQ, PQmed are the median PQ values of healthy children of age selected. Results: The duration of the PQ in groups G1 and G2 was 0.13 (0.11; 0.14) s; and 0.13 (0.12; 0.14) s, respectively, which is statistically significantly less than in patients of groups G3-0.14 (0.13; 0.15] s, p = 0.01. The duration of the sPQ segment in children of groups G1 and G2 was also generally shorter than in patients of groups G3, and amounted, respectively, to 0.05 (0.04; 0.06) s, 0.04 (0.04; 0.05) s, and 0.06 (0.04; 0.07) s, p = 0.02. The rPQ increased progressively as TI decreased and amounted in G1 to 92.9 (85.7; 106.3) %, in G2 100.0 (92.9; 103.0) %, and in G3 104 (100.0; 107.7) %, p = 0.009. A statistically significant negative correlation between IT and PQ-r = −0.23, p = 0.02; with sPQ-r = −0.20, p = 0.045; and with rPQ-r = −0.25, p = 0.01 was revealed. Conclusion: A decrease in TI in asthmatics children is associated with a prolongation of the PQ. This may indicate a slowdown in supraventricular conduction in patients with uncontrolled asthma and, thus, be considered as a risk for the formation of subsequent supraventricular arrhythmias.
