FROM OUR EXPERTS
Since July of 2006, I have been experiencing very strange visual sensations (deja vu - seeing repetitive visions of experiences or thoughts regarding insignificant people that I have known in my life as well as physiological changes (a perceived drop in blood pressure, face paling, etc.) during numerous very short 20 to 30 second episodes. These episodes occur 4 to 5 times a year - usually seasonal and I experience about 10 -15 of them over the course of 2 days or so each time. A headache usually precedes them as does a change in my taste buds (things are tasteless or metallic tasting for a couple of days). After the episodes begin to wane (very few after a day or so), I experience a heightened sense in everything (an alertness, a heightened awareness of life). I went to see a neurologist a couple of years ago and he felt they were a type of migraine. I am experiencing them today (it's a weirdness I find difficult to explain but at times they are very fear provoking)...
Much like heart attacks , strokes are due to a decreased blood flow through an artery. In a matter of seconds brain tissue begins to die if its blood supply is decreased. High blood pressure (hypertension) is a major risk factor for both heart attacks and strokes. Over time, those with hypertension are at risk of developing cholesterol buildup of their arteries. If this occurs in the heart, angina or heart attacks can result. In the neck or head, a stroke is possible. This is the most common type of stroke, known as an ischemic stroke. It is due to decreased blood flow through arteries to the brain. An artery can be blocked by cholesterol buildup (plaque) or sudden blockage from blood clotting inside the vessel ( thrombosis ). Alternatively, it can be due to a blood clot, thrombus, breaking of and traveling into smaller vessels to block their blood flow. This latter process is known as embolization. Another type of stroke is due to bleeding, known as a hemorrhagic str...
There are times it is normal for the heart to beat harder, such as if you are out hiking and encounter a bear. Your blood pressure will jump so larger levels of oxygenated, nutrient rich blood is sent through your system and you are able to react. All part of the flight or fight response.
When you are diagnosed for high blood pressure your blood pressure is not just high for limited periods of time. It is consistently elevated. This means the heart is constantly working harder than it should.
Here are 7 reasons your heart may be dealing with this increased workload:
1. Atherosclerosis (narrowing of the arteries) - This may be caused by cholesterol deposits along arterial walls resulting in plaque buildup. Fibrosis or endothelial dysfunction may also result in narrower arteries. When arteries narrow the heart has to pump harder (exert more force) to move blood throughout the system.
2. Overweight and obesity - Fat is a tissue that requires a constant blood s...
