Can varicose veins be cured?
Cure is not the best way to describe it but the point of the question is - can they be treated and the answer is yea- absolutely and easily in the hands of someone who understands venous physiology and not just someone who know how to use devices. The options for type of treatment depend on the exact findings on duplex ultrasound and patient’s symptoms. READ MORE
Do you need to have surgery if you have gallstones?
No, millions of people have gallstones. The only reason to have the gallbladder removed is if there are symptoms - 1) biliary colic where you have pain every time you eat a fat containing meal or sometimes a non-fat meal, or 2) the gallbladder get infected due to a gallstone obstructing the outflow duct, the cystic duct READ MORE
When does an echo test and stress test show a heart problem?
At first glance, a 37 year old man would not be normally expected to have coronary artery disease but there are exceptions and outliers. Generally speaking, a stress test is to see if under a physiologic stress of increased work by the heart to exercise or a pharmacological induced stress in people who cannot exercise, the heart demonstrates ischemia, which is an inability to increase blood flow to the heart to meet the increased demand. If this test is negative then one can generally rule out significant coronary artery disease. There are three kinds of stress tests - treadmill, nuclear medicine, and a dobutamine stress echocardiogram. All have their advantages and limitations but if one of these is done And Is negative, one can generally rule out coronary artery disease as a cause. The standard echocardiogram is to evaluate cardiac function and valvular function and structure. If that’s normal, then one can exclude this as a cause of symptoms. The one thing that these tests do not evaluate is rhythm disorders which are usually episodic and if this is suspected then one needs to have an ambulatory monitor which is worn for a period of time, sometimes even 30 days and if one develops symptoms, then that time is correlated with the rhythm to see if they are linked. Gastrointestinal symptoms can mimic cardiac symptoms as well. And to true other question that you posed the stress test and echo are done at baseline not when one has symptoms- that’s not necessary. The rhythm monitoring is done to see if, when symptoms develop, there is a coincident abnormal rhythm such as an abnormal fast heart rate. Hope that answers the question adequately.

What is claudication?
Claudication is a symptom of inadequate blood flow to the lower extremities upon exertion. It comes from the Latin word claudicatio which means to lomp. The typical symptom is that of walking a certain distance followed by aching, fatigue, or discomfort, and occasionally pain, in the calves that resolves completely upon cessation of walking. It can affect the hips and the buttocks as well in certain conditions where the arteries that are involved are in the pelvis. But typically it relates to a condition where the blood flow to the leg is adequate at rest but when one exercises the muscles in the leg, the blood flow cannot increase to the point where it needs to because of narrowing in the arteries due to atherosclerotic plaque. This condition can be mimicked by symptoms due to lower back nerve impingement. But generally speaking, it is always the same distance every time before the symptoms come on and once the patient stops walking, the symptoms resolve completely. It should not require a change in posture or position to make the pain or discomfort go away. Niren Angle, MD, RVT, FACS READ MORE
