New Algorithm for the Prediction of Cardiovascular Risk in Symptomatic Adults with Stable Chest PainPapireddy, Muralidhar R., Lavie, Carl J., Deoker, Abhizith, Mamudu, Hadii, Paul, Timir K. 01 May 2018 (has links)
Purpose of Review: To review the landmark studies in predicting obstructive coronary artery disease (CAD) in symptomatic patients with stable chest pain and identify better prediction tools and propose a simplified algorithm to guide the health care providers in identifying low risk patients to defer further testing. Recent Findings: There are a few risk prediction models described for stable chest pain patients including Diamond-Forrester (DF), Duke Clinical Score (DCS), CAD Consortium Basic, Clinical, and Extended models. The CAD Consortium models demonstrated that DF and DCS models overestimate the probability of CAD. All CAD Consortium models performed well in the contemporary population. PROMISE trial secondary data results showed that a clinical tool using readily available ten very low-risk pre-test variables could discriminate low-risk patients to defer further testing safely. Summary: In the contemporary population, CAD Consortium Basic or Clinical model could be used with more confidence. Our proposed simple algorithm would guide the physicians in selecting low risk patients who can be managed conservatively with deferred testing strategy. Future research is needed to validate our proposed algorithm to identify the low-risk patients with stable chest pain for whom further testing may not be warranted.

Den diagnostiska säkerheten i arbetsprov på kvinnor med angina pectoris : SlutversionAzadan, Niaz January 2020 (has links)
Angina pectoris är bröstsmärta orsakat av myokardischemi, till följd av kranskärlsjukdom med eller utan stenoser eller icke kranskärlsjukdom. Arbetsprov är den vanligaste undersökningen för angina pectoris. Diffusa symtom och angina pectoris varianter utan stenoser med låg sensitivitet för elektrokardiografi (EKG) sänker den diagnostiska säkerheten i arbetsprov på kvinnor. Litteraturstudiens syfte var att utreda om hemodynamiska parametrar och riskbedömning med Pre-test sannolikhet (PTP) samt Dukes Löpbands Index (DTS, Dukes Treadmill Score) kan öka den diagnostiska säkerheten i arbetsprov på kvinnor. Inklusionskriterierna var vetenskapligt granskade kliniska studier på engelska, med information om etiskt godkännande eller samtycke. Snowballing metoden, PUBMED, MEDLINE och CINAHL användes. Studier som inkluderades i resultatet granskades återigen och jämfördes med varandra. Hemodynamiska parametrar, PTP och DTS ökar den diagnostiska säkerheten i arbetsprov på kvinnor. Denna diagnostiska säkerhet beror dock också på PTP metod, PTP riskgrupp, etnicitet och angina pectoris variant. Vidare forskning behövs om etnicitetspecifika PTP metoder, mekanismen bakom blodtrycksreaktionen, DTS på icke kranskärlsjukdomar samt metoder som kan skilja mellan olika icke kranskärlsjukdomar. Utan studier om Systematic COronary Risk Evaluation (SCORE) och Diamond Forrester Score (DFS) samt deras påverkan på arbetsprov, kan inte resultatet i litteraturstudien generaliseras till arbetsprov i Sverige. / Angina pectoris is chest pain and myocardial ischemia due to Coronary Artery Disease (CAD) or Non-Coronary Artery Disease (non-CAD). Exercise stress test (EST) is the most common diagnostic procedure for angina pectoris. Non-CAD, low sensitivity for exercise electrocardiography (ex-ECG) and diffuse symptoms lower the diagnostic accuracy for females. This review’s aim was to study whether haemodynamic parameters and risk stratifications with Pre-test probability (PTP) or Duke Treadmill Score (DTS) improves the diagnostic accuracy of EST for females. Inclusion criterions were English peer reviewed, clinical studies with mentioned ethical approval or consent. Snowballing, PUBMED, MEDLINE and CINAHL were used. Articles that were included in the results, were reviewed once again, and compared to one another. Hemodynamic parameters, PTP and DTS increase the diagnostic accuracy of EST in women. This diagnostic accuracy depends on PTP method, risk group, ethnicity, and angina pectoris variant. Further research regarding ethnic specific PTP methods, mechanism behind the blood pressure reaction, DTS for diagnosis of non-CAD and methods for differentiation of subtypes of non-CAD, would be valuable. Without studies about the Systematic Coronary Risk Evaluation (SCORE), Diamond Forrester Score (DFS), and their impact on ex-ECG, the result of this review cannot be generalized to ex-ECG in Sweden.
