[Eosinophilic cation protein and development of restenosis of drug covered stents].
Kardiologiia. 2011; 51(6): 49-54
Gabbasov ZA, Kozlov SG, Saburova OS, Imaeva AE, Bosykh EG, Liakishev AA, Zykov KA, Masenko VP
Aim of the study was to assess activation of eosinophils as well as allergic and inflammatory reactions of the body in development of restenosis after implantation of stents with drug covering. We included into the study 32 patients with ischemic heart disease (IHD) and stable angina subjected to repeat coronary angiography during first year after endovascular myocardial revascularization with the help of stents with drug covering, and 11 healthy persons. Levels of eosinophilic cation protein (ECP), immunoglobulin E (IgE), and C-reactive protein (CRP) in blood plasma of patients and healthy persons was determined by immunoenzyme assay. According to results of angiographic study patients were divided into 2 groups: the first comprised 19 patients in whom no instent restenosis was found, the second comprised 13 patients in whom formation of restenosis at least in one stent was noted. Patients in these groups did not differ by age, sex, smokers and nonsmokers ratio, presence of hyperlipidemia, and angiographical characteristics of involved arteries. In patients with restenosis of stents blood plasma ECP level was 17.7 (11.2-24.0) g/ml and significantly higher than in patients without restenosis [9.0 (6.4-12.9) g/ml; p=0.017]. Blood level of IgE in these groups of patients did not differ [58.8 (42.1-164.0) and 52.9 (12.8-76.1) mg/ml, respectively; p=0.40] and did not differ from IgE level in blood of healthy volunteers [32.0 (21.2-80.8) mg/ml; p=0.91]. CRP level in patients with IHD was higher than in healthy volunteers [0.36 (0.1-0.75) mg/ml; p=0.0008)], but did not differ significantly in groups of patients with and without restenosis [2.38 (0.30-4.08) and 1.63 (0.61-2.47) mg/ml, respectively; p=0.52]. It was found that in the group of patients with low blood level of ECP (<11 g/ml) restenoses were revealed in 19% while in the group with higher blood level of ECP (>11 g/ml) - in 62% of cases (p=0,019). In patients subjected to coronary stenting with higher level of ECP in blood we noted more frequent development of restenoses than in patients with low level of this protein. The data obtained allow to suggest presence of relationship between development of restenosis and elevated activity of eosinophilic granulocytes in patients with IHD after revascularization.

Open Question: Lyme disease or something more? Doctors, please help?
Doctors answers are greatly appreciated.
I’ll try to keep this as short as possible.. I was bit by a tick in mid-July of this year. I had bulls eyes and everything. I had nausea, fatigue, stomach pains, head aches, and for the first two days I had heart palpitations. My doctor, who is young and great, is very convinced that I have Lyme.
Three days after being bit I took two Lyme tests, one being the western blot. Both negative.
Every since I was bit my stomach pains have worsened. It’s to the point were I’m almost in tears. (and I’m a strong girl, I can handle pain. I play Ice Hockey) The pain is everywhere in my stomach. But the two worst spots are I guess were my spleen would be. On my front under my left rib cage and up a little higher to my left side, right by my breast. It’s like a stabbing pain!!
My BM’s use to be very normal. Now it’s unpredictable.. Sometimes I can’t go at all during the day and sometimes I go three times a day. Sometimes it’s normal stool, sometimes its very very soft (runny).
Last week I had the same two Lyme tests plus a liver failure test, some sort of intestine test, and he wanted to check my white cell count. All were normal and fine except the white cell count. The nurse said it was a fraction high,but nothing to worry about.. okay fine. Obviously my body is trying to fight something off.
Obviously without seeing me in person its hard to diagnose, and that’s not really what I’m looking for. I’m looking for some suggestions on what it might be. What are your opinions on the white blood cell, the sharp pain, and the possibility of this still being Lyme or something else?
I’m 19, in college, and I’m going to be honest, this is effecting my studying… I’m trying very hard to overcome whatever is going on in my body but I’m at the point where I’m just so frustrated, and tired, and scarred of what the answer might be..
Also, I don’t think I have this and I don’t know if it means anything, but cancer does run in the family. My great grandmother and aunt both had ovarian cancer (one lived, the other died from it), my great grandfather had colon and rectal cancer (dead), and now my other great grandmother has tumors, we don’t know if they’re cancerous yet.
Thank you so much
I was put on Doxycycline right away. But my doctor took me off because my stomach pains were getting worse and he wasn’t able to tell if it was from the medication or from the bite. I was also put on a medication for my stomach pains by a different doctor about two weeks ago and it didn’t help.. He said its strong and should take the pains away. Yeah, no.. It’s only getting worse with each passing day.

Clinical benefits of the addition of lower extremity low-intensity resistance muscle training to early aerobic endurance training intervention in patients with coronary artery disease: A randomized controlled trial.
J Rehabil Med. 2011 Sep; 43(9): 800-7
Hansen D, Eijnde BO, Roelants M, Broekmans T, Rummens JL, Hensen K, Daniels A, Van Erum M, Bonné K, Reyckers I, Alders T, Berger J, Dendale P
Objective: Muscle resistance training is often combined with aerobic endurance training during rehabilitation of patients with coronary artery disease. However, the clinical effects of additional lower-extremity low-intensity muscle resistance training during early rehabilitation (within the first month after coronary revascularization) in patients with coronary artery disease remain unclear. Design: Prospective randomized controlled trial. Subjects: Sixty patients with coronary artery disease. Methods: Subjects were randomly assigned to early aerobic endurance training (n = 30) or combined aerobic endurance and resistance muscle training (n = 30). Subjects performed 18 (standard deviation 2) exercise sessions (at 65% VO2peak, for 40 mins/session). In resistance muscle training, additional low-intensity (12-20 repetition maximum) resistance muscle exercises were performed. The following parameters were evaluated: exercise capacity, body composition, blood lipid profile, glycaemic control, blood endothelial progenitor cell and cytokine content, and muscle performance. Results: A total of 47 patients with coronary artery disease completed the intervention. Total body lean tissue mass tended to increase with greater magnitude (p = 0.07), and blood high-density lipid cholesterol content increased with significantly greater magnitude in resistance muscle training (p

Voting Question: Questions about old age/dementia?
I recently got back from a trip to visit my grandma and grandpa, who are 80 and 84. My grandma is in fantastic shape and if you were to talk to hear on the phone, you’d have no idea that she is he age. My grandpa is a different story. He’s always been overweight and enjoyed a sedentary life-style. About 10 years ago, his health started taking a significant effect, and through the years he’s become more and more immobile, but he’s always been sharp and simply put happy.
The last few years he’s been in a wheelchair, but when I visited him, I noticed the mental affects. He now has dementia and can barely hold a conversation. He’s practically a vegetable at this point and his good moments only come in spurts. While he is in good spirits, he did tell my uncle that he’s in living hell right now.
Now to my actual questions:
1. Do most people who have Alzheimer/dementia suffer? I mean, like someone who isn’t in a wheelchair and can be a little more active.
2. If you are over 85 and are not at risk of cancer/heart disease, will you die from dementia? It seems like those are the only ways to really go from what I’ve seen and it seems like lossing your mind is absolutely terrifying.
Thanks for the help.

Effects of fasting and/or postprandial glucose on heart rate recovery in patients with coronary heart disease.
Diabetes Metab. 2011 Aug 23;
Gayda M, Bourassa MG, Tardif JC, Fortier A, Juneau M, Nigam A
AIM: The impact of both fasting and postprandial glycaemia on heart rate recovery (HRR) has not been studied in patients with coronary heart disease (CHD). For this reason, we sought to determine the relationships between HRR and both fasting and postprandial glycaemia. METHODS: A total of 4079 patients with baseline fasting plasma glucose (FPG) levels and 706 patients with 2-hour postprandial glucose (2hPG) levels were identified from the Coronary Artery Surgery Study registry, a database of 24,958 patients with suspected or proven CHD who had undergone cardiac catheterization between 1974 and 1979. Median long-term follow-up was 14.7 years (interquartile range: 9.8-16.2 years). The relationships between HRR and both FPG and 2hPG were studied. RESULTS: In univariate analyses, increasing levels of both FPG and 2hPG were significantly associated with lower HRR. In multivariate models adjusted for age, exercise tolerance in METs, resting heart rate and maximum systolic blood pressure during exercise testing, FPG remained significantly associated with HRR while 2hPG did not. CONCLUSION: Both raised FPG and decreased HRR are independent predictors of total and cardiovascular (CV) mortality in subjects with CHD. Our data suggest that the mortality risk associated with elevated FPG may in part be due to deleterious effects on autonomic regulation of CV function, as reflected by lower HRR. Further studies are required to determine whether or not non-pharmacological and/or pharmacological treatments of increased fasting glucose have a beneficial influence on HRR.

Management of patients with atrial fibrillation: specific considerations for the old age.
Cardiol Res Pract. 2011; 2011: 854205
Haegeli LM, Duru F
Atrial fibrillation (AF) is the commonest of all sustained arrhythmias, and most of the patients seeking medical therapy are in the elderly age group. The management of these patients is particularly difficult due to associated comorbidities. Hypertension, congestive heart failure, left ventricular hypertrophy, and coronary artery disease are often present in the elderly patient population, and therefore, antiarrhythmic drugs often fail due to side effects, proarrhythmia, or poor rhythm control. Recently, radiofrequency catheter ablation has been widely performed as an efficient therapy for recurrent, drug-refractory AF. Nevertheless, patients at old age were underrepresented in prior AF ablation trials, and the current guidelines for catheter ablation of AF recommend a noninvasive approach in the elderly patient group due to the lack of clinical data supporting ablation therapy. However, study results of our group and others are suggesting that catheter ablation is a safe and effective treatment for patients over the age of 65 years with symptomatic, drug-refractory AF, and therefore, patients should not be precluded from catheter ablation only on the basis of age. This paper discusses the pharmacological (rhythm control, rate control, and anticoagulation) and catheter management of AF in the elderly population.
