The danger with UNCONTROLLED hypertension is an increase in systemic vascular resistance (systole pressure) increases left atrial pressure relative to right atrial pressure, resulting in a left-to-right shunt depending on size of aneurysm ; and a decrease in systemic vascular resistance (vasogenic shock) decreases left atrial pressure relative to right atrial pressure, resulting in a right-to-left shunt.
How does hyperthyroidism affect the heart, and what cardiovascular changes happen if a cat with HOCM goes from hyperthyroid to euthyroid? For instance, how are systemic vascular resistance, blood volume, stroke volume, cardiac output, etc affected. I am wondering if an HOCM heart relies on a hyperdynamic state from hyperthyroidism, and if going euthyroid will harm the cat.
For the right heart this is the pulmonary vascular bed, creating Pulmonary Vascular Resistance (PVR), while for the systemic circulation this is the systemic vascular bed, creating Systemic Vascular Resistance (SVR). The vessels actively change diameter under the influence of physiology or therapy, vasoconstrictors decrease vessel diameter and increase resistance, while vasodilators increase vessel diameter and decrease resistance.
While surgical repair usually abolishes the aortic arch gradient, systemic blood pressure often remains abnormal and may increase with time, even in those who became normotensive early after repair. The mechanisms for these abnormalities of long-term blood pressure regulation remain unclear. Furthermore, treatment in later life may be less effective, as long-term studies have shown persistent hypertension and decreased survival in those who were operated on in adolescence and adulthood.
Hi,
The medication's generic name is "Nebivolol". It's Brand Name is Nebilet, you may have the spelling off a little.
From what I read, the drug "is a so-called vasodilating beta blocker. Thus, in contrast to traditional beta blockers, it is more patient friendly in that it maintains systemic flow and blood flow to target organs, lowers vascular resistance, and has very little, if any, metabolic adverse effects," Messerli explained.
Hi Kumar,
I am not a doctor, therefore I cannot answer your question in any scientific/medical terms. Your best bet would be to check with a doctor or peruse professional medical literature to find more specific explanations.
My understanding of insulin resistance is narrowed down to the basic concept, which is that in insulin resistance patients the muscle, fat and liver cells don't use insulin properly causing excess glucose to bulid up in the blood.
t smoke, do exercise, am thin). My doctor put me on a diuretic, Tekturna and Bystolic, and within a week I had completely lost my sense of taste! Anyone else experienced this? I'm wondering if it's a side effect that will wear off if I just stick it out. The combination seems to be working well to lower my bp and hr but I'm losing weight (a bad thing) and really, really miss food!
Allergies can cause arterial muscle spasm, resulting in increased peripheral vascular resistance and an increase in blood pressure. Also, anxiety can also raise the blood pressure.
Hope this helped and do keep us posted.
If the right heart failure is due to pulmonary hypertension, then NO, it may not improve, and could actually be a contraindication to ASD closure (depending upon your degree of left to right shunting through the ASD and how abnormal is the pulmonary vascular resistance).
Your pulse may increase very much but the systemic vascular resistance will fall with recruitment of very large muscles such those found in your as legs and back.
You are only 30 and unlikely to have coronary artery disease. A stress test is only indicated if you have symptoms suggestive of ischemia, such as chest pain or pressure.
You maximum heart rate is not usually achieved during a stress test, as we normally stop after 85% MPHR ( which is 220- age= 180 ).
Absolute contraindications include active infection, untreated malignancy, coexisting systemic illness likely to limit survival, severe and irreversible major organ dysfunction or fixed elevated pulmonary vascular resistance.
Relative contraindications, on the other, include: advanced age, recent or unresolved pulmonary infection, active peptic ulceration, marked peripheral or cerebrovascular disease or mental illness. These conditions may vary from one institution to another.
I am confused as to what microvascular angina and insulin resistance have to do with each other. I am pre-diabetic, 35 lbs overweight, 50 yo female. If I can get my blood sugar down, will I see an improvement in chest pain???
I've never had any type of fungal infection in my life as I'm too acidic. My bicarbonate labs are always just under the range. I've had insulin resistance for decades due to eating too much sugar and my kidneys aren't up to scratch.
My mother had severe systematic yeast infections which vanished when she started betaine HCL with pepsin supplements to increase stomach acid.
Thanks for using the forum. I am happy to address your questions, and my answer will be based on the information you provided here. Please make sure you recognize that this forum is for educational purposes only, and it does not substitute for a formal office visit with your doctor.
Without the ability to examine you and obtain a history, I can not tell you what the exact cause of your symptoms is nor can I make specific recommendations.
The common (spontaneous atherosclerosis) pathophysiologic mechanisms, namely, endothelial injury with early platelet involvement and subsequent progressive smooth muscle cell proliferation and thrombosis leading to vascular occlusion. Understanding the mechanisms of this process has made it possible to include strategies to limit vascular injury and reduce subsequent thrombotic and proliferating cellular responses.
DIETARY IRON OVERLOAD INDUCES VISCERAL ADIPOSE TISSUE INSULIN RESISTANCE ASSOCIATED WITH HYPER-RESISTINEMIA, AND SYNERGIZES WITH OBESITY AND FATTY LIVER IN INDUCING SYSTEMIC INSULIN RESISTANCE

Background & Aims: Insulin resistance is the key pathogenic feature underlying nonalcoholic fatty liver disease and the metabolic syndrome.
The general formula for determining tolerable heartrates during exercise is:
Take the number 220
Deduct your age.
Multiply by .6
Multiply again by .85
As we age the maximum tolerable heartrate decreases. High heart-rates result in insufficient filling of the ventricles. They also result in increased disposition to the condition known as ventricular fibrillation.
Blood pressure pulse is the difference between systole and diastole calculation i.e. 120-80=40 (normal) and I believe if the calculation exceeds 60 there may be a problem. However, I don't believe you have any problem with your blood pressure...it isn't static and the variations can be due to many benign circumstances....there my be some worry if blood pressure pulse is consistently high. It would be a good indication of a vascular disease and usually seen with older people.
If your son feels sick, I think it could be something systemic. Because I feel sick and have swollen ankles (at the end of the day), and wrists, too. My doctors do not know what is wrong, either.
Are your sons wrists swollen and do they feel hard like a muscle swelling, or soft like fluid swelling? My ankles are soft but my wrists have hard swelling like a swollen muscle, but it does not hurt.
Press inbto the swelling with your finger for about a minute.
Your MRI shows age related atrophy changes that could be limited to temporal and parietal lobes depending on whether you have suggestion of alzheimer’s disease, frontal and temporal lobes in frontotemporal lobar degeneration, and global atrophy if there is vascular dementia. These need to be clinically correlated if you have any senile cognitive changes.
