<p style="text-align:justify"><span style="font-size:16px"><span style="font-family:&quot;Times New Roman&quot;,serif"><span style="color:#000000"><strong><span style="font-family:Calibri,sans-serif"><span style="color:black">Methods: </span></span></strong><span style="font-family:Calibri,sans-serif"><span style="color:black">A&nbsp;total of<strong> </strong>1,000 videos were analyzed, corresponding to the first 100 search results on YouTube with the terms (in Portuguese): &ldquo;cardiac + arrest&rdquo;; &ldquo;heart + attack&rdquo;; &ldquo;heart + thrombosis&rdquo;; &ldquo;coronary + thrombosis&rdquo;; &ldquo;infarction &ndash; brain&rdquo;, &ldquo;myocardial + infarction&rdquo;, and &ldquo;acute + myocardial + infarction&rdquo;. Irrelevant (n=316), duplicated (n=345), without audio (n=24) or non-Portuguese (n=106) videos were excluded. Included videos were evaluated for source, topic, target audience, and scientific inaccuracies. The quality of information was assessed using The Health on the Net Code (HONCode from 0 to 8) and the DISCERN (from 0 to 5) scores &ndash; the higher, the better quality.</span></span></span></span></span></p>

<p style="text-align:justify"><span style="font-size:16px"><span style="font-family:&quot;Times New Roman&quot;,serif"><span style="color:#000000"><strong><span style="font-family:Calibri,sans-serif"><span style="color:black">Results: </span></span></strong><span style="font-family:Calibri,sans-serif"><span style="color:black">242 videos were included (mean duration 9.2&plusmn;0.8 minutes, minimum 0.3 and maximum 89.3 minutes), with a total of 2,226 minutes. The majority were published by independent instructors (n=95, 39%) and were addressed to the general population (n=202, 83.5%). Videos from independent instructors received the best approval by the public </span>(like/dislike ratio of<em> </em>43.7 (19.4</span><span style="font-family:Symbol">-</span><span style="font-family:Calibri,sans-serif">76.7)). Videos from personal experience had the most views (63,304.52 views,111.5</span><span style="font-family:Symbol">-</span><span style="font-family:Calibri,sans-serif">683,598.3) and comments (69 comments, 2&ndash;593). Videos from television shows had a significant larger number of views (11,396, 1,462</span><span style="font-family:Symbol">-</span><span style="font-family:Calibri,sans-serif">49,073) compared to videos from news channels (291, 15</span><span style="font-family:Symbol">-</span><span style="font-family:Calibri,sans-serif">1.083 views, <em>p</em>=0.001), pharmaceutical industry (70, 25</span><span style="font-family:Symbol">-</span><span style="font-family:Calibri,sans-serif">128 views, <em>p</em>=0.010), and scientific societies (234, 58</span><span style="font-family:Symbol">-</span><span style="font-family:Calibri,sans-serif">12,963 views, <em>p</em>=0.026). The most discussed topic was &ldquo;signs and symptoms&rdquo; (62%, n=150). One third of the videos<span style="color:black"> (n=79) had inaccuracies; however, videos from scientific societies and governmental/health institutions had no inaccuracies. The mean video quality was poor or moderate (</span>HONCode score 3.0&plusmn;1.1, DISCERN 2.4&plusmn;0.7)<span style="color:black">; only one video had good quality without inaccuracies. Governmental/health institutions were the source with best quality videos (HONCode&nbsp; 4&plusmn;1, DISCERN 2&plusmn;1). </span></span></span></span></span></p>

As the average video quality was low it is important to define strategies to improve the quality of the available onlinehealth information.</span></span></span></span></span></p>
