Blood Pressure Inquiry
First of all, thank you for trying to donate blood. Its an wonderful way to give back to society. I hope you will continue to do so. I recommend you check your blood pressure every morning. This will normalize the activity for you and reduce your anxiety about it. Keep a log of your readings and take it with you to your appointment with your physician. There you can discuss lifestyle changes to improve your blood pressure obesity, sleep apnea, high salt intake are common drivers of high blood pressure. READ MORE
Can I drink alcohol with a heart stent?
Yes you can drink alcohol in moderate. The American Heart Association recommends no more than 1 drinkday for women and 2 drinksday for men. READ MORE
Reaction to the heat?
The symptoms you describe may be related to dehydration related to the heat. Good idea to find ways to cool down. Also be mindful to drink more water on hot days. The blood pressure readings you listed are high. Be sure to check your blood pressure when you are seated and calmly at rest. If the readings remain high greater than 14090, talk to your doctor about treatment options. READ MORE
Blood pressure?
The lisinopril can help lower the blood pressure, but likely wont do much to lower your heart rate. Best to get back on your metoprolol as soon as possible, then your doctor can adjust dose to control your blood pressure. READ MORE
What could it be or should I see somebody?
It sounds as though you should definitely see someone about your symptoms. The headache that radiates down to your neck is likely unrelated to your heart condition. I suggest you address these with your primary care physician. Your cardiologist needs to address your congestion, atrial fibrillation and high blood pressure. Isosorbide is not sufficient on its own to treat severe heart failure. READ MORE
Are Lysinoprl and 200 MGs potassium supplements in electrolytes ok to take together?
Lisinopril can raise your serum potassium. The small amount of potassium in an electrolyte supplement is unlikely to be enough to push your serum potassium to dangerously high levels. The safest course of action is to have your blood drawn to check your potassium level. It should ideally be between 3.5 and 5.2 mg/dL. READ MORE
What are the potential cardiac causes for chest tightness?
The most common cardiac cause of chest tightness or pressure is angina which is caused by restriction of the blood flow to the heart muscle. The most common cause of angina is coronary artery disease which involves narrowing of the arteries by plaque build up. Features of angina are typically chest pain/heaviness/tightness/pressure which comes on with exertion and improves with rest. While there are other non-cardiac causes of chest tightness, it's a good idea to discuss the symptoms with a healthcare professional to determine the cause. READ MORE
What is the treatment for mitral valve prolapse?
There is no specific treatment for mitral valve prolapse (MVP). Many patients with MVP have no symptoms and in most who have symptoms they are benign. Follow-up echocardiogram testing is reasonable to evaluate for the development of mitral regurgitation (leaking of the mitral valve). In a small subset of patients with MVP who develop severe mitral regurgitation, surgery is necessary to repair or replace the valve. READ MORE
What are your thoughts on the use of wearable technology for monitoring heart health?
Wearables are becoming ever more popular and reliable. The most important factors impacting heart health are age, gender, ethnicity, family history, tobacco use, diabetes, high blood pressure, high cholesterol and obesity. Some of these cannot be modified (e.g. age, ethnicity and family history). Others (like tobacco use and obesity) don't need wearables to track their control. I'm not aware of a reliable wearable to monitor blood pressure or cholesterol, but would love to see one developed. So, using wearables that can track sleep, activity, heart rate and blood sugar all can give a sense of one's heart health. Some of the heart rate trackers can provide an alert for an abnormal rhythm and some can even display a short rhythm strip (a short image of the electrical signal - like an EKG). READ MORE
How can high cholesterol affect my heart health?
Elevated cholesterol, particularly elevated LDL cholesterol, can lead to atherosclerosis (plaque deposition in the arteries) which can lead to heart attack, stroke or claudication depending on which arteries are most affected. Controlling your cholesterol, along with aerobic exercise, blood sugar control, blood pressure control, avoiding nicotine products and maintaining a healthy weight are all part of a heart healthy lifestyle to reduce those risks. READ MORE
Are there any specific lifestyle changes I should be aware of to ensure the success of my heart stent?
A heart healthy lifestyle includes a primarily plant-based whole food diet, regular exercise (at least 150 minutes/week), maintaining a healthy weight, getting plenty of sleep, and abstinence from tobacco and recreational drugs. READ MORE
How long do the effects of a heart stent last?
A stent in the coronary artery (which supplies blood to part of the heart muscle) can last a lifetime. There is a 2-3% chance of re-narrowing (called restenosis) within the first 6-9 months. And there is a risk of thrombosis (clotting) which is why your cardiologist will recommend you take two antiplatelet medications for 6-12 months after your stent is placed. In order to reduce the risk of restenosis or worsening of plaque in the remainder of the arteries to the heart, your cardiologist will also recommend several things: 1. lowering your LDL cholesterol to <70, 2. good blood pressure and blood sugar control, 3. exercise, 4. maintaining a healthy weight and 5. abstinence from tobacco. READ MORE
Is it normal to hear your heartbeat when exercising?
Its not unusual to hear your heart beat when you have something covering your ear. The carotid artery runs near the ear canal, so it makes sense that you can hear the heartbeat when the EarPods are in READ MORE
Sore throat
Yes READ MORE
chest pain
In light of the stuffy nose, you most likely have a respiratory infection which is causing your chest tightness when you breathe. Please test for COVID. Most viral infections resolve over 7-10 days. If your symptoms worsen or you become short of breath, see your local physician. READ MORE
Is this an emergency
Blood pressure that high needs to be treated. It may be a side effect of the vyvanse. Talk to your doctor about stopping or changing meds and monitoring your blood pressure READ MORE
Heart rate
A resting heart rate of 53bpm indicates good cardiovascular health. Getting your heart rate up to 155bpm during exercise is perfectly normal. READ MORE
Resting Heart rate below 60
A resting heart rate less than 60 is perfectly normal and a sign of your cardiovascular fitness. Continue your excellent exercise regimen. READ MORE
Restarting interrupted high blood pressure medications
A week should be sufficiently long for the medications to take maximal effect. READ MORE
Heart rate
A resting heart rate in the 50s is perfectly normal for someone taking metoprolol. No reason to worry. READ MORE
