📌 ماهو الفرق بين
ventricular hypertrophy and ventricular dilatation ?!

🔹ventricular hypertrophy  》is due to pressure overload as in aortic stenosis or S-HTN

🔹ventricular dilatation 》is due to volume overload as in case of increase venous return,ex: increase IV fluids administration

🔸in ventricular hypertrophy 》no displacement of apex beat only forcefull beat

🔸in ventricular dilatation 》displacement of apex beat

🔹ventricular hypertrophy 》
_preserved ejection fraction
_diastolic HF

🔹ventricular dilatation 》
_reduced ejection fraction
_systolic HF

🔸causes of ventricular hypertrophy:
》anything increases AFTERLOAD as
_HTN
_AS
_PS
》other causes as
أي حاجه بتقلل إمتلاء الventricles أثناء الdiastole مثل
احتشاء عضلة القلب بسوائل cardiac temponade
أو تليف restrictive cardiomyopathy
أو زيادة في سمك العضلة نفسها HOCM
أو زيادة في سمك الغشاء حول العضلة constrictive pericarditis

🔸causes of ventricular dilatation:
》anything increases PRELOAD as
_hyperdynamic circulation as : hypervolemia, anemia, thyrotoxicosis
_AR
_PR

》other causes as hypothyroidism
أي مرض بيوسع عضلة القلب مثل
حدوث إلتهاب في عضلة القلب نفسها myocarditis
أو خلل وظيفي في انقباض عضلة القلب لأي سبب مثل DCM

Soloviev also promoted the channel in a post he shared on his own Telegram, which has 580,000 followers. The post recommended his viewers subscribe to "War on Fakes" in a time of fake news. During the operations, Sebi officials seized various records and documents, including 34 mobile phones, six laptops, four desktops, four tablets, two hard drive disks and one pen drive from the custody of these persons. Official government accounts have also spread fake fact checks. An official Twitter account for the Russia diplomatic mission in Geneva shared a fake debunking video claiming without evidence that "Western and Ukrainian media are creating thousands of fake news on Russia every day." The video, which has amassed almost 30,000 views, offered a "how-to" spot misinformation. Right now the digital security needs of Russians and Ukrainians are very different, and they lead to very different caveats about how to mitigate the risks associated with using Telegram. For Ukrainians in Ukraine, whose physical safety is at risk because they are in a war zone, digital security is probably not their highest priority. They may value access to news and communication with their loved ones over making sure that all of their communications are encrypted in such a manner that they are indecipherable to Telegram, its employees, or governments with court orders. Markets continued to grapple with the economic and corporate earnings implications relating to the Russia-Ukraine conflict. “We have a ton of uncertainty right now,” said Stephanie Link, chief investment strategist and portfolio manager at Hightower Advisors. “We’re dealing with a war, we’re dealing with inflation. We don’t know what it means to earnings.”
