How did the COVID-19 pandemic affect the referral patterns for SPECT myocardial perfusion? A single center experience

Objective(s): We evaluated the impact of the COVID-19 pandemic on the number of referrals for SPECT myocardial perfusion imaging (SPECT-MPI) as well as changes in the clinical and imaging characteristics.Methods: We respectively reviewed 1042 SPECT-MPI cases performed in a 4-month period during the...

description Objective(s): We evaluated the impact of the COVID-19 pandemic on the number of referrals for SPECT myocardial perfusion imaging (SPECT-MPI) as well as changes in the clinical and imaging characteristics.Methods: We respectively reviewed 1042 SPECT-MPI cases performed in a 4-month period during the COVID-19 pandemic (PAN; n=423) and compared their findings with those acquired in the same months before the pandemic (PRE; n=619).Results: The number of stress SPECT-MPI studies performed during the PAN period significantly dropped compared to the number of studies carried out in the PRE period (p = 0.014). In the PRE period, the rates of patients presenting with non-anginal, atypical and typical chest pain were 31%, 25% and 19%, respectively. The figures significantly changed in the PAN period to 19%, 42%, and 11%, respectively (all p-values

Regarding the pretest probability of coronary artery disease (CAD), a significant decrease and increase were noticed in patients with high and intermediate pretest probability, respectively (PRE: 18% and 55%, PAN: 6% and 65%, p &lt;0.001 and 0.008, respectively). Neither the rates of myocardial ischemia nor infarction differed significantly in the PRE vs. PAN study periods.Conclusion: The number of referrals dropped significantly in the PAN era. While the proportion of patients with intermediate risk for CAD being referred for SPECT-MPI increased, those with high pretest probability were less frequently referred. Image parameters were mostly comparable between the study groups in the PRE and PAN periods.</description><identifier>ISSN: 2322-5718</identifier><identifier>EISSN: 2322-5726</identifier><identifier>DOI: 10.22038/AOJNMB.2023.68394.1475</identifier><language>eng</language><publisher>Mashhad, Iran: Mashhad University of Medical Sciences</publisher><subject>covid-19 ; myocardial perfusion imaging ; spect-mpi</subject><ispartof>Asia oceania journal of nuclear medicine and biology, 2023-01, Vol.11 (2), p.128-134</ispartof><oa>free_for_read</oa><woscitedreferencessubscribed>false</woscitedreferencessubscribed></display><links><openurl>$$Topenurl_article</openurl><openurlfulltext>$$Topenurlfull_article</openurlfulltext><thumbnail>$$Tsyndetics_thumb_exl</thumbnail><linktopdf>$$Uhttps://www.ncbi.nlm.nih.gov/pmc/articles/PMC10261691/pdf/$$EPDF$$P50$$Gpubmedcentral$$H</linktopdf><linktohtml>$$Uhttps://www.ncbi.nlm.nih.gov/pmc/articles/PMC10261691/$$EHTML$$P50$$Gpubmedcentral$$H</linktohtml><link.rule.ids>230,314,724,777,781,882,27905,27906,53772,53774</link.rule.ids></links><search><creatorcontrib>Ataei Nakhaei, Saeedeh</creatorcontrib><creatorcontrib>Askari, Emran</creatorcontrib><creatorcontrib>Mohammadzadeh, Hadis</creatorcontrib><creatorcontrib>Roustaei, Hesamoddin</creatorcontrib><creatorcontrib>Karamian, Farivash</creatorcontrib><creatorcontrib>Mostafavi, Sayyed Mostafa</creatorcontrib><creatorcontrib>Aghaei, Atena</creatorcontrib><title>How did the COVID-19 pandemic affect the referral patterns for SPECT myocardial perfusion?
