SPECT blood flow improves per-vessel sensitivity of myocardial perfusion imaging to detect ischemia
26Objectives: SPECT myocardial blood flow (MBF) imaging can be performed using modern solid state SPECT cameras. It is an additive technique to traditional relative myocardial perfusion imaging (MPI). The additional clinical benefit of MPI remains to be proven and its promise is largely based on prior PET MBF data (1,2,3). We sought to determine whether SPECT MBF would improve the sensitivity of ischemia detection by MPI. Methods: Consecutive patients undergoing clinical SPECT MPI had MBF performed. A comprehensive electronic medical record review was undertaken to determine 12-month cardiovascular follow-up. In patients who underwent anatomical downstream testing, absolute MBF was calculated for the global left ventricle and individual myocardial vessels (LAD, LCx and RCA) at rest and stress. SPECT findings (MBF and MPI) were evaluated on a per-vessel and per-patient analysis. Results: 195 patients were included with a mean age of 71 years old. Indications for SPECT MPI were chest pain (20%), previous percutaneous coronary intervention (PCI; 15%), and dyslipidemia (10%). 25 patients without prior CABG had downstream anatomical testing with invasive or CT coronary angiography. Global and per-vessel values for MBF were defined in 7 patients who had non-obstructed or normal coronaries. Per-patient and per-vessel analysis demonstrated improved sensitivity of MBF to detect stenosis ≥ 70% in comparison to MPI: per-patient MBF 85% versus 77% for MPI (p
Meeting of the Working Group on the National Mental Health Strategic Plan, April 2019By Saima Wazed and Nazish ArmanDHAKA, Oct 27 2021 (IPS) Mental health is a state of well-being when both your body and your mind are in balance, and you are able to deal with the difficulties and challenges that come your way and easily find joy, peace, and happiness once the challenge is overcome. For many people though, the challenges often remain for too long – the pain of losing someone you dearly loved, being diagnosed with a chronic disease like cancer or a heart condition, losing your family/home/job or feeling like you failed...
When treating pain in multiple sclerosis, a specialist is urging colleagues to think outside the box - especially since pain can evolve over time due to changes in MS and related conditions.Medscape Medical News

OBJECTIVES: Previous findings suggest that abusive supervision, i.e., subordinates' perceptions of their supervisor's behaviours as hostile (excluding physical aggression), may increase the risk of health complaints. In addition, recent data suggest that ...
