Right now, millions of students across the country are participating in physical activities at their schools - a basketball or soccer game, football and cheerleading practice or gym class. What if one of them had a life-threatening cardiac emergency? Would the school be prepared?Sudden cardiac arrest strikes more than 340,000 Americans each year, including children and teens, usually without warning. Heart conditions tend to go undetected and often manifest themselves during physical activity. In the event of a cardiac arrest, a quick response and the early use of an automated external defibrillator (AED) are critical to improving the chances of survival.According to the American Heart Association, early use of AEDs - portable devices that analyze the heart's rhythm and deliver an electric shock to reestablish a normal heartbeat -could raise the chance of survival by 20 percent or more. "Nearly 95 percent of cardiac arrest victims die - usually because defibrillation occurs too late," said Dr. Vincent Mosesso Jr. of the National Center for Early Defibrillation based at the University of Pittsburgh. "Every minute that passes before returning the heart to a normal rhythm decreases the chance of survival by 10 percent. Patients who receive CPR [cardiopulmonary resuscitation] and a defibrillator shock within three minutes of going into sudden cardiac arrest have the best odds of survival."Unfortunately, many schools aren't equipped with AEDs.For that reason, Duracell and Zoll Medical Corp. have teamed up to help inform parents and educators about the importance of being prepared for these critical situations. "Through this campaign, we want to work with communities across the country to provide their schools with the tools necessary to help save lives," said Kara Salzillo, manager of brand communications for Duracell.
Pheochromocytoma is an important cause of secondary Hypertension. We have adnenal gland located at upper portion of each kidney. It is divided into adrenal cortex and adrenal medulla. Pheochromocytoma is a tumor of Adrenal Medulla. Normal function of adrenal medulla is to produce epinephrine or adrenaline. Which is responsible for controlling blood pressure and to help cope with stressful situations.So majority of symptoms of pheochromocytoma are due to excess secretion of adrenaline from adrenal medulla. Most patients of pheochromocytoma have recurrent episodes of headache, sweating and a feeling of high anxiety. The following symptoms are listed from the most common to the least commonHeadaches (severe) sweating Episodes (generalized) heart palpitations (tachycardia and palpitations) Anxiety nervousness (feelings of impending death) tremors Pain in the lower chest or upper abdomen Nausea (with or without nausea) Weight loss Heat intolerance These symptoms may come by situations which causes pressure over tumor like physical activity, exercise, defecation, anesthesia, or change in body position.Who should be examined for PheochromocytomaThose who have uncontrolled hypertensionThose who have age between 40 and 60Those who are already taking 4 antihypertensive drugs but blood pressure is not controllable.Those who have episodes of above symptomsCause of pheochromocytoma is unknown, however some forms of this tumor runs in families like,a-Multiple endocrine neoplasia, type II (MEN-II). In addition to a pheochromocytoma, people with MEN-II also have thyroid cancer. Other forms of MEN-II include pheochromocytoma with thyroid cancer and hyperparathyroidism (MEN-IIA), and pheochromocytoma with thyroid cancer and tumors of nerves in the eyes lips, mouth and digestive tract (MEN-IIB). b-Neurofibromatosis 1 (NF1). Pheochromocytomas can occur in a small percentage of people with NF1, a syndrome that includes multiple tumors in the skin (neurofibromas), pigmented skin spots, tumors of the optic nerve of the eye, and bone diseases. c-Von Hippel-Lindau (VHL) disease. People with this rare multi system disorder are at high risk of pheochromocytoma brain eye and kidney tumors.Most pheochromocytomas are benign tumors and they don't spread to other parts of body however some forms do show metastasis (spread) to other parts of body like lungs, bones and brains. Usually only one gland is involved however this tumor can be present in both adrenal glands.Investigations:Blood and Urine tests: We perform blood and urine tests to diagnose pheochromocytoma. 24 hr urine collection is tested for epinephrine, norepinephrine and dopamine. This test is called VMA. Idea is just to check level of epinephrine and its metabolites in urine. If these are detected in urine in excess quantity, then tumor is diagnosed.Abdominal scan. Now you have diagnosed tumor by blood and urine tests, after that to find out location of tumor, do Ultrasound, CT scan of abdomen.Complications:If high blood pressure remained uncontrolled it may lead to complications of heart failure, infarction, cerebrovascular accident, vision damage and kidney failure.Treatment:First treatment is to control high blood pressure with medication like Alpha Blockers and Beta Blockers. When epinephrine is secreted by this tumor it acts on alpha and beta receptors present on heart and blood vessels, result is vasoconstriction and increase heart rate. Now if if we take drugs like alpha blocker and beta blocker, epinephrine will be blocked by these drugs to act on these receptors so result is vasodilation and slow heart rate. Common Alpha blockers are Prazosin (Minipress), Terazosin (Hytrin) Phenoxybenzamine( Dibenzaline). Common Beta Blockers are Atenolol(Tenormin), Carvedilol(Carveda), Metoprolol(Mepressor), Inderal.Treatment of choice for this tumor is Surgery. After removal of this gland by surgery, blood pressure becomes normal with a day. There are two types of surgeries. General and Laproscopic surgery. However Surgery is not an option for those tumors which show metastasis to other parts of body. For that we use chemotherapy and radiations.Whenever you have high blood pressure with any symptom, don't ignore it, you may be the patient of Pheochromocytoma. Always contact your Doctor.If you want to know more about Pheochromocytoma, visit our site highbloodpressuremed.com
We all know that keeping up with our heart health is an important thing to do. We all know that there are a wide variety of factors that cause heart problems, and we should know by now that there are some basic ways to help protect the health of our hearts. What many people do not realize, however, is that keys to their "heart health" may be different than keys to the heart health of others.There are almost as many strategies and tips for having good heart health as there are people with hearts in the world.

The most important factor for improving cardiorespiratory fitness (cardio or CR) is the intensity of the workout. Changes in CR fitness are directly related to how "hard" an aerobic exercise is performed. The more energy expended per unit of time, the greater the intensity of the exercise, the greater the effect on "cardiorespiratory fitness" .You have to know how hard is "hard" to determine if an "aerobic exercise" like running is producing a CR training effect or if it's just burning a few calories. The heart rate during work or exercise is an excellent indicator of how much effort you are exerting. Only by keeping track of your heart rate during a workout can you be sure that the intensity is enough to improve your CR fitness level. In other words, your ability to monitor your heart rate is the single most important key to success in CR training.Training Heart Rate (THR) = Desired Intensity of the WorkoutTHR is the heart rate at which you need to exercise to get a training effect. The U.S. Army fitness gurus have given us two methods to determine THR. The first method, percent maximum heart rate (%MHR) is simpler to use, while the second method, percent heart rate reserve (%HRR) is more accurate.%MHR MethodWith this method the THR is figured using the estimated maximal heart rate. You can estimate your maximum heart rate (MHR) by subtracting your age from 220. Thus, a 20 year old would have an estimated maximum heart rate (MHR) of 200 beats per minute (220 - 20 = 200).A person who is in poor shape should exercise at 70 percent of his MHR; if he is in relatively good shape, at 80 percent MHR; and, if he is in excellent shape, at 90 percent MHR.Examples:A 20 year old in good physical condition would have a THR of 160 beats per minute (BPM). 220 - 20 = 200 * .80 = 160 BPM.A 30 year old in good physical condition would have a THR of 152 beats per minute (BPM). 220 - 30 = 190 * .80 = 152 BPM.A 40 year old in poor physical condition would have a THR of 126 beats per minute (BPM). 220 - 40 = 180 * .70 = 126 BPM.%HRR MethodA more accurate way to calculate THR is the %HRR method. The range from 60 to 90 %HRR is the THR range in which people should exercise to improve their CR fitness levels. If you know your general level of CR fitness, you can determine which percentage of HRR is a good starting point for you. For example, a person in excellent physical condition could start at 85 percent of his HRR; if he is in reasonably good shape, at 70 percent HRR; and, if he is in poor shape, at 60 percent HRR.Most CR workouts should be conducted with the heart rate between 70 to 75 percent HRR to attain, or maintain, an adequate level of fitness. A person who has reached a high level of fitness may derive more benefit from working at a higher percentage of HRR, particularly if he cannot find more than 20 minutes for CR exercise.Exercising at any lower percentage of HRR than 60 does not give the heart, muscles, and lungs an adequate training stimulus. Exercising at more than 90 percent can be dangerous. Before anyone begins aerobic training, he should know his THR (the heart rate at which he needs to exercise to get a training effect).The example below shows how to figure the THR by using the resting heart rate (RHR) and age to estimate heart rate reserve (HRR). A 20 year old in reasonably good physical shape is the example.STEP 1: Determine the MHR by subtracting your age from 220. i.e. MHR = 220 - 20 = 200.STEP 2: Determine the resting heart rate (RHR) in beats per minute (BPM) by counting the resting pulse for 30 seconds, and multiply the count by two. A shorter period can be used, but a 30 second count is more accurate. This count should be taken while you are completely relaxed and rested. For this example we use a RHR of 69 BPM.STEP 3: Determine the heart rate reserve (HRR) by subtracting the RHR from the estimate MHR. i.e. HRR = 200 - 69 = 131 BPMSTEP 4: Calculate THR by (1) multiplying HRR by the relative fitness level as a percentage and (2) adding the result to the HRR. For example, our 20 year old in good physical condition will exercise at 70% HRR.(1) .70 * 131 = 91.7(2) 91.7 + 69 = 160.7In summary, a reasonably fit 20-year-old with a resting heart rate (RHR) of 69 BPM has a training heart rate (THR) goal of 161 BPM.During aerobic exercise, the body will usually have reached a "Steady State" after five minutes of exercise, and the heart rate will have leveled off. At this time and, immediately after exercising, is when you should monitor your heart rate to see if you are within your desired THR range.If your pulse rate is below the THR, you must exercise harder to increase your pulse to the THR. If your pulse is above the THR, you should reduce the intensity to reduce the pulse rate to the THR goal.
As you know, there is a direct connection between stress and blood pressure. A stressful lifestyle is generally accepted to be a major cause of hypertension and a host of other illnesses. In fact, people are often not very surprised when they learn that someone in a high-profile, high-stress job or business also suffers from high blood pressure. It is practically expected that he or she will have the condition. Stress-induced hypertension can lead to cardiac problems which may compromise your health for the rest of your life. Because of the demands of their business, many busy executives dont eat right or exercise. This results in unhealthy weight gain. When you add excessive levels of job related stress into the mix, you have a perfect recipe for several health problems. High blood pressure increases the load on vital organs of the body. Organs like the kidneys and the heart may become so overloaded that they no longer function properly. While they are not definite indicators, some of the symptoms of "high blood pressure" include feelings of lethargy and low energy, increased frequency of urination, severe headaches, giddiness and nausea. What can someone in a high-stress occupation do to avoid hypertension? It may not always be possible to avoid stressful situations, but you can take steps to minimize the impact. Ask yourself, have you created a work environment where you are thought to be indispensable in your job? Do you or others feel that work will never get done without your direct presence and intervention? That sort of environment can generate plenty of stress and send your blood pressure levels dangerously high. Acknowledge that no one is indispensable and that life and business will go on without you. In any case, you will serve your work better if you dont drive stress levels high for yourself or others. Often, it is a matter of defining your priorities. Give some serious thought to what is really important to you. Not what you think others expect of you. If what you have is out of alignment with what you want, start to make changes. If you think you are overloaded at work, ask that some of your duties be given to others in your office. Consult your doctor about the ideal weight for you and if necessary, begin a weight reduction program under his supervision. Find out from your doctor what exercise program will suit you best. Make a commitment to exercise regularly and do it. If your doctor recommends dietary changes such as limiting salt intake to reduce the risk of hypertension, stick to it. Many people claim that regular meditation can help lower blood pressure. Even five to ten minutes a day can help. You need not do any esoteric tricks to get the benefits of meditation. Keep it simple. Sit in a comfortable position, relax your body and mind and quiet your thoughts as much as possible. If you prefer, quietly watch your breath flow in and out, without attempting to control it in any way. Dont get worked up about the fact that you cant relax completely or reach perfect stillness of mind. Thats not required in any case. A series of small changes will add up to a major difference in your state of health. Do what is necessary to limit both "stress and blood pressure" to manageable levels.
