Heart disease is the principal cause of mortality and the major contributor to reduced quality of life. The electrocardiogram is used to monitor the cardiovascular system. The correct classification of the beats in electrocardiograms gives an opportunity to have treatment more focused. The manual analysis of the ECG signals faces different problems. For this reason, automated diagnosis systems are fed by ECG signals to detect anomalies. In this paper, we propose a method based on a novel preprocessing approach and neural networks for the classification of heartbeats which is able to classify five categories of arrhythmias in accordance with the AAMI standard. The preprocessing stage allows each beat to have “P wave-R peak-R peak” information. We evaluated the proposed method on the MIT-BIH database, which is one of the most used databases. According to the results, the proposed approach is able to make predictions with the average accuracies of 97%. The average accuracies are compared to different approaches that use different preprocessing and classifier stages. Our approach is superior to that of most of them.

This coronary heart disease can be solved with non-surgical called percutaneous coronary intervention. This action will be normalized the quality of perfusion in the coronary arteries, which would certainly have an impact on the quality of life of patients. The research objective was to observe the patient of quality of life after treatment on intervention percutaneous coronary. The research design was cross sectional. There were 50 respondents taken by consecutive sampling. Data were collected in outpatient room in RSUP Dr. Hasan Sadikin Bandung, who have came with treatment routine schedule after percutaneous coronary intervention during November 1st–14th 2013. The questionnaire use WHOQOL-BREF format with 26 questions that consisting of 4 domains of quality of life: physical domain, psychological domain, social domain, and environment domain. Majority of patients were male (74 %), with the range of age mostly 56-66 years ( 34 % ), married ( 96 % ), college education was the highest ( 66 % ), the majority had not a primary job like as housewife , retired, student, etc. ( 26 % ). Data were collected using the questionnaire WHOQOL – BREF. The result have shown that rates of quality of life was good ( 50 % ) and health condition after percutaneous coronary intervention neither satisfied nor dissatisfied ( 44 % ). Nurses have a role in helping patients achieve optimal quality of life like giving information to patient correctlyKey words: Percutaneous coronary intervention, quality of life, WHOQOL – BREF

Prevalensi Penyakit Jantung Koroner (PJK) terus mengalami peningkatan setiap tahunnya dan menjadi masalah kesehatan utama di masyarakat saat ini. PJK berdampak terhadap berbagai aspek kehidupan penderitanya baik fisik, psikososial maupun spiritual yang berpengaruh terhadap kualitas hidup pasien. Isu kualitas hidup dan faktor-faktor yang berhubungan didalamnya belum tergambar jelas di Indonesia. Tujuan dari penelitian ini adalah mengidentifikasi faktor yang memengaruhi kualitas hidup pada pasien PJK yang sedang menjalani rawat jalan. Faktor-faktor yang diteliti dalam penelitian ini meliputi jenis kelamin, tingkat penghasilan, revaskularisasi jantung, rehabilitasi jantung, kecemasan, depresi dan kesejahteraan spiritual. Kecemasan diukur dengan Zung Self-rating Anxiety Scale, depresi diukur dengan Beck Depression Inventory II, kesejahteraan spiritual diukur dengan kuesioner Spirituality Index of Well-Beingdan kualitas hidup diukur menggunakan Seattle Angina Questionnaire. Penelitian ini menggunakan rancangan kuantitatif deskriptif dan analitik multivariatedengan regresi logistic. Diteliti pada 100 responden yang diambil secara randomdalam kurun waktu 1 bulan di Poli Jantung. Hasil penelitian menunjukkan faktor yang memengaruhi kualitas hidup pada pasien PJK adalah cemas (p) 0,002; Odd Ratio(OR) 4,736 (95% confidence interval(CI), 1,749 – 12,827); depresi (p) 0,003; OR 5,450 ( 95% CI, 1,794 – 16,562); dan revaskularisasi (p) 0,033; OR 3,232 (95% CI, 1,096 – 9,528). Depresi menjadi faktor yang paling berpengaruh terhadap kualitas hidup pasien PJK. Faktor yang memengaruhi kualitas hidup pada pasien PJK meliputi depresi, cemas dan revaskularisasi. Dari ketiga variabel tersebut depresi merupakan variabel yang paling signifikan berpengaruh, sehingga manajemen untuk mencegah depresi perlu mendapatkan perhatian lebih baik lagi dalam discharge planningataupun rehabilitasi jantung.Kata kunci: Cemas, depresi, faktor yang memengaruhi, kualitas hidup, spiritual.Factors Influenced the Quality of Life among Patients Diagnosed with Coronary Heart Disease AbstractCoronary Heart Disease (CHD) has affected multidimensional aspects of human live nowadays. Yet, quality of life and factors associated with quality of life among people who live with heart disease has not been explored in Indonesia. This study aimed to identify factors influenced the quality of life among people with CHD received outpatient services. Those factors are gender, income, revascularization, cardiac rehabilitation, anxiety, depression and spiritual well-being. Zung Self-rating Anxiety Scale was used to measure anxiety where depression level measured using Beck Depression Inventory II. Spirituality index was used to measure spiritual well-being. The quality of life level was measured using the Seattle Angina Questionnaire. This study used quantitative descriptive with multivariate analysis using logistic regression. 100 respondents were randomly selected from the Cardiac Outpatient Unit. Findings indicated factors influenced the quality of life of CHD patients using a significance of ƿ-value < 0.005 were: anxiety (ƿ=0,002, OR = 4,736, 95% CI, 1,749 – 12,827); depression (ƿ=0,003; OR=5,450, 95% CI, 1,794 – 16,562); and revascularizations (ƿ=0,033; OR=3,232, 95% CI, 1,096 – 9,528). Depression was considered as the most significant factor; therefore, managing depression is a priority in the discharge planning or cardiac rehabilitation programme. Keywords: Anxiety, depression, quality of life, spiritual, well-being.

Abstract Background Recurrent spontaneous epistaxis is the most common clinical manifestation and the most debilitating symptom in hereditary haemorrhagic telangiectasia (HHT) patients. To this date, there exist only a classification of HHT patients by different genetic mutations. There is no standard classification for the mucocutaneous endonasal manifestations of HHT. The aim of the present study was to document the variety of endonasal HHT lesions using digital microscopy and to propose a clinical classification. Methods We recorded the endonasal HHT lesions of 28 patients using a digital microscope. We reconstructed the 3D images und videos recorded by digital microscope afterwards and classified the endonasal lesions of HHT in two classes: Grade A, presence of only flat telangiectasias in the mucosa level and Grade B, (additional) presence of raised berry or wart-like telangiectasia spots. We investigated also Haemoglobin level by routine laboratory procedures, plasma VEGF level by ELISA, Severity of epistaxis by epistaxis severity score (ESS) and quality of life by a linear visual analogue scale (VAS). Results We found a higher quality of life and a lower severity of epistaxis in Grade A patients in comparison to Grade B patients. No difference in plasma VEGF level and in Haemoglobin between Grad A patients and Grade B patients could be detected. Plasma VEGF levels showed no gender specific differences. It could also not be correlated to the extranasal manifestation. Conclusion The classification for endonasal manifestation of HHT proposed in this study indicates severity of epistaxis und quality of life. Digital microscopy with the ability of 3D reconstruction of images presents a useful tool for such classifications. The classification of endonasal HHT lesions using digital microscopy allows to evaluate the dynamic of HHT lesions in the course of time independent of examiner. This allows also to evaluate the efficacy of the different treatment modalities by dynamic of HHT lesions. Moreover digital microscopy is very beneficial in academic teaching of rare diseases.
