A modular cluster based collaborative recommender system for cardiac patients

Publication date: Available online 16 November 2019Source: Artificial Intelligence in MedicineAuthor(s): Anam Mustaqeem, Syed Muhammad Anwar, Muhammad MajidAbstractIn the last few years, hospitals have been collecting a large amount of health related digital data for patients. This includes clinical test reports, treatment updates and disease diagnosis. The information extracted from this data is used for clinical decisions and treatment recommendations. Among health recommender systems, collaborative filtering technique has gained a significant success. However, traditional collaborative filtering algorithms are facing challenges such as data sparsity and scalability, which leads to a reduction in system accuracy and efficiency. In a clinical setting, the recommendations should be accurate and timely. In this paper, an improvised collaborative filtering technique is proposed, which is based on clustering and sub-clustering. The proposed methodology is applied on a supervised set of data for four different types of cardiovascular diseases including angina, non-cardiac chest pain, silent ischemia, and myocardial infarction. The patient data is partitioned with respect to their corresponding disease class, which is followed by k-mean clustering, applied separately on each disease partition. A query patient once directed to the correct disease partition requires to get similarity scores from a reduced sub-cluster, thereby improving the efficiency of the system. Each disease part...

Publication date: Available online 3 December 2019Source: Journal of Cardiology CasesAuthor(s): Kazunori Takemura, Masaharu Maegaki, Ryuta Nakamura, Tetsuro Takase, Kaneto Mitsumata, Tomoaki Tanabe, Imun TeiAbstractSpontaneous coronary artery dissection (SCAD) usually occurs in women, which can result in significant morbidities. A 38 year-old obese man who is currently smoking was referred to our hospital with chest pain. His electrocardiography and echocardiography suggested myocardial infarction in proximal region of left coronary artery. Emergent coronary angiography revealed 99% stenosis at mid portion of LAD and diffu...

Abstract Ventricular free wall rupture is a fatal mechanical complication of acute myocardial infarction. In some cases it can be represented as subacute clinic and may not cause death in a few minutes. Acute pseudo-aneurysms are extremely unstable and bound to fatal rupture. Herein we report a male patient who suffered dyspnea and mild chest pain, 4 weeks after acute ST-segment elevation myocardial infarction.

CONCLUSION: The results of this study indicated that there was a relationship between MAU and CSFP and confirmed that endothelial dysfunction is a contributing factor to CSFP. These findings are of utmost importance due to the prognostic value of MAU for both all-cause and cardiovascular mortality rates. PMID: 31802772 [PubMed - in process]

Introduction: Patients undergoing peripheral vascular surgery (PVS) have increased risk of post-op myocardial infarction (MI) and death due to coronary artery disease (CAD). Functionally significant coronary ischemia is often unrecognized since guidelines recommend no cardiac testing in patients with no CAD symptoms. A new non-invasive cardiac test, coronary CT angiography (CTA)-derived fractional flow reserve (FFRCT), reliably identifies ischemia-producing coronary stenosis in chest pain patients but its value in peripheral vascular patients is unknown.

The headline in a main Finnish newspaper on 16 November announced: “Trust and interest for published science has increased in Finland”. I would have hypothesized that evidence-based knowledge was losing the game against the rush of non-scientific and commercial information – but I was wrong. A 3-year follow-up survey among the Finland population was clear on this. Could the growth in electronic and social media information actually be causing people to search for knowledge based on scientific facts? Forty-five years have passed since the publication of the first issue of the Scandinavian Journal of Work...

An elderly woman with a h/o myocardial infarction presented with 2 hours of burning substernal chest pain.Here is her ECG:Is there an OMI?What is the best next strategy to assess for OMI?ECG description:There is sinus rhythm.  There are well-formed Q-waves in inferior leads, with some minimal ST Elevation, and reciprocal ST depression in aVL.  The STE with STD in aVL is typical of inferior OMI, right?Exceptfor the well-formed Q-waves, which suggest anold inferior MI.There is also anearly R/S transition in precordial leads, with alarge R-wave in V2.  This suggestsprevious posterior MI as well.  (Bayes de...

Objective: comparative assessment of the QoL and mental status in patients with COPD who had suffered from STEMI.Material and Methods: The I group consists of 50 patients with COPD +STEMI (37 - males, mean age -52.5 ± 10.8 years): group A - 20, group B – 14, group C – 11, group D – 5 (GOLD, 2018). The II group -54 patients without COPD, comparable in age, sex and location of MI. The questionnaires "SF-36 Health Status Survey" (SF-36) and CAT were used to assess the QoL of COPD patients.
