Additionally, the cardiovascular system has many interconnected parts that not only affect the heart but other parts of the body. When heart valve disease becomes more advanced, unexpected problems can arise, and patient concerns associated with stroke and blood pressure can elevate.<\/p>\n<p>We received an interesting patient question from Patty related to this topic about how changes in one\u2019s condition relate to the progression of heart valve disease. Patty asked, \u201cMedication has maintained my blood pressure for several years. A sudden drop took place a month ago. My cardiologist paused my blood pressure medication. However, it has remained low for a month or so. My valve is now at a severe stage. Do blood pressure readings have a significant role in determining the progression of heart valve disease? And do these fluctuations increase stroke risk?\u201d <\/p>\n<p>To answer Patty\u2019s question, we met with <a href=\"https:\/\/www.heart-valve-surgery.com\/surgeons\/dr-Patrick-McCarthy-Chicago-Illinois.php\">Dr. Patrick McCarthy,<\/a> the Executive Director of the Bluhm Cardiovascular Institute at Northwestern Medicine in Chicago, Illinois.

Usually, it\u2019s a different mechanism that controls your blood pressure. There are conditions like a leaky aortic valve where blood flows backwards through the aortic valve, which may drop the lower number, the diastolic number, on your blood pressure. If you have severe aortic stenosis where the valve doesn\u2019t open very well, blood pressure could potentially drop. With both of those conditions, if they\u2019ve progressed to that phase, then it is time to be thinking about having surgery. If your doctor thinks the blood pressure is related to the heart valve disease, then that is an indication.\u201d<\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<p style=\"text-align: center;\"><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-6118 aligncenter\" src=\"https:\/\/www.heart-valve-surgery.com\/learning\/..\/Images\/dr-patrick-mccarthy-headshot.jpg\" alt=\"\" width=\"129\" height=\"152\" \/><a href=\"https:\/\/www.heart-valve-surgery.com\/surgeons\/dr-Patrick-McCarthy-Chicago-Illinois.php\">Dr. Patrick McCarthy<\/a><\/p>\n<p>&nbsp;<\/p>\n<ul>\n<li>How is blood pressure related to stroke risk? \u201cCan blood pressure changes cause a stroke or contribute to it? It certainly can,\u201d said Dr. McCarthy. \u201cYou don\u2019t want your blood pressure too high because that can cause a stroke, where you can have a bleed into the brain. If it\u2019s too low, you may not get perfusion to the brain. Anytime that you\u2019re running a low blood pressure, you need to be carefully assessed.\u201d<\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-6119 aligncenter\" src=\"https:\/\/www.heart-valve-surgery.com\/learning\/..\/Images\/stroke-risk-drawing.jpg\" alt=\"Stroke Risk Drawing\" width=\"650\" height=\"362\" \/><\/p>\n<p>&nbsp;<\/p>\n<h2>Thanks Dr. McCarthy and Northwestern Medicine!<\/h2>\n<p>On behalf of all the patients in our community, thank you, <a href=\"https:\/\/www.heart-valve-surgery.com\/surgeons\/dr-Patrick-McCarthy-Chicago-Illinois.php\">Dr. Patrick McCarthy<\/a>, for everything you and your team are doing at Northwestern Medicine in Chicago, Illinois!<\/p>\n<p>Related links:<\/p>\n<ul>\n<li><a href=\"https:\/\/www.heart-valve-surgery.com\/learning\/afib-stroke-risk-reduction\/\">Stroke Risk Reduction for Heart Valve &amp; Atrial Fibrillation Patients<\/a><\/li>\n<li><a href=\"https:\/\/www.heart-valve-surgery.com\/learning\/scar-tissue\/\">Ask Dr. McCarthy: Scar Tissue &amp; Minimally-Invasive Heart Valve Reoperations<\/a><\/li>\n<li><a href=\"https:\/\/www.heart-valve-surgery.com\/learning\/what-can-patients-expect\/\">Doctor Q&amp;A: What Can Heart Surgery Patients Expect In The Hospital?<\/a><\/li>\n<\/ul>\n<p>Keep on tickin,<br \/>\nAdam<\/p>\n<p>P.S.
