Study of histocompatibility antigens of the HIA system in 86 patients with rheumatic fever has demonstrated the high rate of the antigens AII, B27, Cw2, 3, Dr5, 7 as compared with control (600 healthy persons). It is therefore necessary to point to the involvement of the HIA system in the formation of proneness to rheumatic fever and its clinical varieties. Special attention should be drawn to the locus HIA C. Histocompatibility antigens associated with rheumatic fever can be viewed as risk factors which should necessarily be taken into account during the conduction of the primary prophylaxis, especially in children coming from the families whose members are afflicted with rheumatic fever as well as in predicting the character of the disease progress and heart disease formation. The presence in the phenotype of A2, AII, B13, 27, Cw2, 3 is associated with a continuously relapsing disease. A10 occurs only in an acute disease marked by a high degree of activity. Mitral diseases are associated with A9, B27, Cw2, 3 whereas aortal distress with AII, B7, 27 and Cw2. B13, Bw35, Cw2 and Dr7 are mostly demonstrable in patients without any heart disease, Dr4 occurs in diseases characterized by minimal activity.

The A II antagonists (RA II antagonists) are a new group of anti-hypertensive drugs with five years of clinical use. They were investigated after the knowledge of independent ways to get angiotensin II. They block AT1 receptor. It's possible that, after AT1 block, the high plasmatic levels of AII stimulate the AT2 receptors with vasodilation and anti-proliferative activity. We are waiting for the results of several big prospective studies with RA II antagonists on cardiovascular morbidity and mortality. At present time, the first indication for its use is the appearance of cough when taking ACE inhibitors. The association of ACE inhibitors and RA II antagonists can improve some clinical conditions like dilated hypertensive cardiopathy, nephropathy or refractory hypertension.

Altered plasma levels of lipids and lipoproteins, obesity, hypertension, and diabetes are major risk factors for atherosclerotic cardiovascular disease. To identify genes that affect these traits and disorders, we looked for association between markers in candidate genes (apolipoprotein AII (apo AII), apolipoprotein AI-CIII-AIV gene cluster (apo AI-CIII-AIV), apolipoprotein E (apo E), cholesteryl ester transfer protein (CETP), cholesterol 7alpha-hydroxylase (CYP7a), hepatic lipase (HL), and microsomal triglyceride transfer protein (MTP)) and known risk factors (triglycerides (Tg), total cholesterol (TC), apolipoprotein AI (apo AI), apolipoprotein AII (apo AII), apolipoprotein B (apo B), body mass index (BMI), blood pressure (BP), leptin, and fasting blood sugar (FBS) levels.) A total of 1,102 individuals from the Pacific island of Kosrae were genotyped for the following markers: Apo AII/MspI, Apo CIII/SstI, Apo AI/XmnI, Apo E/HhaI, CETP/TaqIB, CYP7a/BsaI, HL/DraI, and MTP/HhpI. After testing for population stratification, family-based association analysis was carried out. Novel associations found were: 1) the apo AII/MspI with apo AI and BP levels, 2) the CYP7a/BsaI with apo AI and BMI levels. We also confirmed the following associations: 1) the apo AII/MspI with Tg level; 2) the apo CIII/SstI with Tg, TC, and apo B levels; 3) the Apo E/HhaI E2, E3, and E4 alleles with TC, apo AI, and apo B levels; and 4) the CETP/TaqIB with apo AI level. We further confirmed the connection between the apo AII gene and Tg level by a nonparametric linkage analysis. We therefore conclude that many of these candidate genes may play a significant role in susceptibility to heart disease.

A heritable deficiency of hepatic lipase (HL) provides insights into the physiologic function of HL in vivo. The metabolism of apolipoprotein B (apoB)-100 in very-low-density lipoprotein (VLDL), intermediate-density lipoprotein (IDL), and low-density lipoprotein (LDL) and of apoA-I and apoA-II in high-density lipoprotein (HDL) particles lipoprotein (Lp)(AI) and Lp(AI:AII) was assessed in 2 heterozygous males for compound mutations L334F/T383M or L334F/R186H, with 18% and 22% of HL activity, respectively, compared with 6 control males. Subjects were provided with a standard Western diet for a minimum of 3 weeks. At the end of the diet period, apo kinetics was assessed using a primed-constant infusion of [5,5,5-(2)H(3)] leucine. Mean plasma triglyceride (TG) and HDL cholesterol levels were 55% and 12% higher and LDL cholesterol levels 19% lower in the HL patients than control subjects. A higher proportion of apoB-100 was in the VLDL than IDL and LDL fractions of HL patients than control subjects due to a lower VLDL apoB-100 fractional catabolic rate (FCR) (4.63 v 9.38 pools/d, respectively) and higher hepatic production rate (PR) (33.24 v 10.87 mg/kg/d). Delayed FCR of IDL (2.78 and 6.31 pools/d) and LDL (0.128 and 0.205 pools/d) and lower PR of IDL (3.67 and 6.68 mg/kd/d) and LDL 4.57 and 13.07 mg/kg/d) was observed in HL patients relative to control subjects, respectively. ApoA-I FCR (0.09 and 0.13 pools/d) and PR (4.01 and 6.50 mg/kg/d) were slower in Lp(AI:AII) particles of HL patients relative to control subjects, respectively, accounting for the somewhat higher HDL cholesterol levels. HL deficiency may result in a lipoprotein pattern associated with low heart disease risk.

With the evolution of transcatheter valve replacement, an important opportunity has arisen for cardiologists and surgeons to collaborate in identifying the criteria for performing these procedures. Therefore, The Society for Cardiovascular Angiography and Interventions (SCAI), American Association for Thoracic Surgery (AATS), American College of Cardiology (ACC), and The Society of Thoracic Surgeons (STS) have partnered to provide recommendations for institutions to assess their potential for instituting and/or maintaining a transcatheter valve program. This article concerns transcatheter pulmonic valve replacement (tPVR). tPVR procedures are in their infancy with few reports available on which to base an expert consensus statement. Therefore, many of these recommendations are based on expert consensus and the few reports available. As the procedures evolve, technology advances, experience grows, and more data accumulate, there will certainly be a need to update this consensus statement. The writing committee and participating societies believe that the recommendations in this report serve as appropriate requisites. In some ways, these recommendations apply to institutions more than to individuals. There is a strong consensus that these new valve therapies are best performed using a Heart Team approach; thus, these credentialing criteria should be applied at the institutional level. Partnering societies used the ACC's policy on relationships with industry (RWI) and other entities to author this document (http://www.acc.org/guidelines/about-guidelines-and-clinical-documents). To avoid actual, potential, or perceived conflicts of interest due to industry relationships or personal interests, all members of the writing committee, as well as peer reviewers of the document, were asked to disclose all current healthcare-related relationships including those existing 12 months before the initiation of the writing effort. A committee of interventional cardiologists and surgeons was formed to include a majority of members with no relevant RWI and to be led by an interventional cardiology cochair and a surgical cochair with no relevant RWI. Authors with relevant RWI were not permitted to draft or vote on text or recommendations pertaining to their RWI. RWI were reviewed on all conference calls and updated as changes occurred. Author and peer reviewer RWI pertinent to this document are disclosed in the Appendices. In addition, to ensure complete transparency, authors' comprehensive disclosure information (including RWI not pertinent to this document) is available in Appendix AII. The work of the writing committee was supported exclusively by the partnering societies without commercial support. SCAI, AATS, ACC, and STS believe that adherence to these recommendations will maximize the chances that these therapies will become a successful part of the armamentarium for treating valvular heart disease in the United States. In addition, these recommendations will hopefully facilitate optimum quality during the delivery of this therapy, which will be important to the development and successful implementation of future, less invasive approaches to structural heart disease.
