Stroke is often due to sudden loss of blood supply to a region of the brain which usually results in paralysis of a part of the body. Stroke could also be due to bleeding into a part of the brain. Strokes and heart disease are linked together in various ways. Stroke can occur after a heart attack as well.
Today’s video is on the subject of stroke and in particular cryptogenic strokes. It is therefore crucial to identify the cause of stroke and treat the underlying cause wherever possible. Strokes are characterised by death of brain cells as a result of disruption of blood supply to those cells.
These harmful substances directly impact the heart and blood vessels in several ways: Reduced Oxygen Supply: Carbon monoxide, a byproduct of smoking, binds to hemoglobin in the blood, reducing its oxygen-carrying capacity. This forces the heart to work harder to supply oxygen to tissues and organs.
High BloodPressure (Hypertension) Persistent high bloodpressure forces the heart to work harder to pump blood. Medications Medications are often the first line of treatment for cardiomegaly and can include: ACE inhibitors or ARBs , which help lower bloodpressure and reduce the workload on the heart.
A new joint guideline from the American Heart Association (AHA), the American College of Cardiology (ACC) and nine other medical societies reports early diagnosis and treatment of peripheral artery disease is essential to improve outcomes and reduce amputation risk, heart attack, stroke and death for people with Peripheral Artery Disease (PAD).
If untreated, AFib can lead to or exacerbate heart failure, and it significantly increases a person’s risk of stroke. This device sits in the heart’s left atrial appendage, where bloodclots often form, to prevent them from getting into the bloodstream. For example, kidney disease is not included in CHA 2 DS 2 -VASc. “The
Hypertension Hypertension, or high bloodpressure , is often referred to as the “silent killer” because it typically shows no symptoms until it leads to more severe health issues. Regular bloodpressure checks and lifestyle modifications, such as a heart-healthy diet and exercise, are essential for managing this risk.
Stroke: Vascular and Interventional Neurology, Volume 3, Issue S2 , November 1, 2023. On arrival, bloodpressure was 165/94 mmHg and blood glucose was 108 mg/dL. He was admitted to the stroke service for work‐up of his abnormal brain vasculature. His NIHSS was 6. CTP showed a core and penumbra volumes of 0 mL.
In some cases, AFib can also increase the risk of stroke, bloodclots and heart failure. Control Underlying Medical Conditions – If you have diabetes, high bloodpressure or other medical conditions that increase your risk of AFib, it’s crucial to manage them properly. How Do You Know If You Have AFib?
February 2024 FDA Approvals: Innovations in Cardiovascular Interventions XACT Carotid Stent System (Approved: 02/07/2024) This approval expands the indications to be used during a Transcarotid Artery Revascularization (TCAR) procedure to prevent future strokes. The label includes a “black box” warning for CV risk due to bloodclots.
Researchers found no significant difference between groups in terms of a composite of death, disabling stroke or rehospitalization for heart failure—which occurred in 9.4% of patients who received the Evolut valve and 10.6% of those receiving the SAPIEN valve. This composite valve function endpoint occurred in 9.4%
Three coronary arteries supply blood to the heart. When one of these arteries becomes completely blocked by a bloodclot, it results in a heart attack, also known as MI (Myocardial infarction). Medical and Surgical Treatment in a Heart Attack An MI occurs when a bloodclot entirely obstructs a blood artery in the heart.
In a cohort of >3,000 people from the National Health and Nutrition Examination Survey (NHANES), sleeping <6 hours each night predicted a higher prevalence of stroke, heart attack, and chronic heart failure. There is a considerable temporal variation in bloodpressure, bloodclotting, and endothelial function.
