It is well known that there are several epidemiologic and demographic factors than influence in the incidence of PEA, like black race and sex, being females more susceptible. There has been also changes in incidence of PEA over the last three decades.
Over the last decades, the incidence of PEA has increased in parallel to a decrease in the incidence of [[VF]] and [[VT]].<ref name="pmid24297818">{{cite journal| author=Myerburg RJ, Halperin H, Egan DA, Boineau R, Chugh SS, Gillis AM et al.| title=Pulseless electric activity: definition, causes, mechanisms, management, and research priorities for the next decade: report from a national heart, lung, and blood institute workshop. | journal=Circulation | year= 2013 | volume= 128 | issue= 23 | pages= 2532-41 | pmid=24297818 | doi=10.1161/CIRCULATIONAHA.113.004490 | pmc= | url=http://www.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=pubmed&tool=sumsearch.org/cite&retmode=ref&cmd=prlinks&id=24297818  }} </ref>  In fact, following adequate management of [[VF]] and [[VT]], the prevalence of VT/VF has dropped by 20% while the prevalence of PEA increased by 11% between 1979 and 2000.<ref name="pmid21060069">{{cite journal| author=Teodorescu C, Reinier K, Dervan C, Uy-Evanado A, Samara M, Mariani R et al.| title=Factors associated with pulseless electric activity versus ventricular fibrillation: the Oregon sudden unexpected death study. | journal=Circulation | year= 2010 | volume= 122 | issue= 21 | pages= 2116-22 | pmid=21060069 | doi=10.1161/CIRCULATIONAHA.110.966333 | pmc= | url=http://www.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=pubmed&tool=sumsearch.org/cite&retmode=ref&cmd=prlinks&id=21060069  }} </ref>  There is a slight female preponderance of PEA.  In addition, PEA is associated with increased age and black race.<ref name="pmid8341333">{{cite journal| author=Becker LB, Han BH, Meyer PM, Wright FA, Rhodes KV, Smith DW et al.| title=Racial differences in the incidence of cardiac arrest and subsequent survival.

===Epidemiological Patterns===
As demonstrated by the workshop made by Myerburg et al <ref name="pmid24297818">{{cite journal| author=Myerburg RJ, Halperin H, Egan DA, Boineau R, Chugh SS, Gillis AM et al.| title=Pulseless electric activity: definition, causes, mechanisms, management, and research priorities for the next decade: report from a national heart, lung, and blood institute workshop. | journal=Circulation | year= 2013 | volume= 128 | issue= 23 | pages= 2532-41 | pmid=24297818 | doi=10.1161/CIRCULATIONAHA.113.004490 | pmc= | url=http://www.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=pubmed&tool=sumsearch.org/cite&retmode=ref&cmd=prlinks&id=24297818  }} </ref>, there has been a decrease of VT/VF as the cause of sudden cardiac arrest, from 70% to 20%- 25%. There was a decrease of 20% of the incidence of VT/VF from 1979-1980 to 1999-2000, supported by observations made by he Seattle study in 2002. In this same study, PEA incidence showed an increase in prevalence of 11%.  Teodorescu et all suggest that one of the causes for the decrease in VF/VT prevalence are due to the strategies against CAD and hyperlipidemia that were taken <ref name="pmid21060069">{{cite journal| author=Teodorescu C, Reinier K, Dervan C, Uy-Evanado A, Samara M, Mariani R et al.| title=Factors associated with pulseless electric activity versus ventricular fibrillation: the Oregon sudden unexpected death study. | journal=Circulation | year= 2010 | volume= 122 | issue= 21 | pages= 2116-22 | pmid=21060069 | doi=10.1161/CIRCULATIONAHA.110.966333 | pmc= | url=http://www.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=pubmed&tool=sumsearch.org/cite&retmode=ref&cmd=prlinks&id=21060069  }} </ref>. Therefore, they hypothesize that the increased incidence of PEA can be explained by a high prevalence of comorbidities or extra cardiac conditions in these patients.

Overview

Over the last decades, the incidence of PEA has increased in parallel to a decrease in the incidence of VF and VT.[1] In fact, following adequate management of VF and VT, the prevalence of VT/VF has dropped by 20% while the prevalence of PEA increased by 11% between 1979 and 2000.[2] There is a slight female preponderance of PEA. In addition, PEA is associated with increased age and black race.[3] [4]


Epidemiology and Demographics

  • The incidence of SCA ranges between 300,000 to 370,000 cases per year, 50% of which are due to PEA.[1]
  • PEA accounts for approximately 20% of out-hospital cardiac arrests and for a third of the in-hospital cardiac arrests.[5] PEA is responsible for 10% of in-hospital deaths.[6]
  • The decrease in the prevalence of VF and VT has been accompanied by a parallel relative increase in the incidence of PEA among patients with SCA.[1] In fact, following adequate management of VF and VT, the prevalence of VT/VF has dropped by 20% while the prevalence of PEA increased by 11% between 1979 and 2000.[2]
  • There is a slight female preponderance of PEA. In addition, PEA is associated with increased age and black race.[3] [4]
