Landmark Article

Comparison of the relation between left ventricular anatomy and QRS duration in patients with cardiomyopathy with versus without left bundle branch block.

By: Chan DD, Wu KC, Loring Z, Galeotti L, Gerstenblith G, Tomaselli G, Weiss RG, Wagner GS, Strauss DG.
Increasing left ventricular (LV) anatomical measurements were associated with increasing QRS duration in patients with cardiomyopathy.

Narrowing sex differences in lipoprotein cholesterol subclasses following mid-life: the very large database of lipids (VLDL-10B).

By: Swiger KJ, Martin SS, Blaha MJ, Toth PP, Nasir K, Michos ED, Gerstenblith G, Blumenthal RS, Jones SR.
The narrowing sex differential in CVD risk after midlife is mirrored by a higher total atherogenic lipoprotein cholesterol burden in women and a closer approximation of the less favorable density phenotype characteristic of men.

Autologous mesenchymal stem cells produce concordant improvements in regional function, tissue perfusion, and fibrotic burden when administered to patients undergoing coronary artery bypass grafting: The Prospective Randomized Study of Mesenchymal Stem...

By: Karantalis V, DiFede DL, Gerstenblith G, et al.

Intramyocardial injection of autologous mesenchymal stem cells into akinetic yet nonrevascularized segments produces comprehensive regional functional restitution, which in turn drives improvement in global LV function.

Does transendocardial injection of mesenchymal stem cells improve myocardial function locally or globally? An analysis from the Percutaneous Stem Cell Injection Delivery Effects on Neomyogenesis (POSEIDON) randomized trial.

By: Suncion VY, Ghersin E, Fishman JE, Zambrano JP, Karantalis V, Mandel N, Nelson KH, Gerstenblith G, DiFede Velazquez DL, et al.

Scar-size reduction and ventricular functional responses preferentially occurred at the sites of transendocardial stem cell injection, compared to nontransendocardial stem cell injection sites.

Myocardial steatosis and its association with obesity and regional ventricular dysfunction: evaluated by magnetic resonance tagging and 1H spectroscopy in healthy African Americans.

By: Liu CY, Bluemke DA, Gerstenblith G, Zimmerman SL, Li J, Zhu H, Lai S, Lai H.
This study found no relationship between cardiac steatosis and left ventricular volumes or ejection fraction, though there is some evidence suggesting that cardiac steatosis may be associated with LV regional function in healthy African-American women.

Intracoronary administration of autologous cardiosphere-derived cells did not raise significant safety concerns.

Metabolic rates of ATP transfer through creatine kinase (CK Flux) predict clinical heart failure events and death.

By: Bottomley PA, Panjrath GS, Lai S, Hirsch GA, Wu K, Najjar SS, Steinberg A, Gerstenblith G, Weiss RG.
Reduced CK flux may be a potential heart failure (HF) treatment target.

Vitamin D deficiency is associated with development of subclinical coronary artery disease in HIV-infected African American cocaine users with low Framingham-defined cardiovascular risk.

By: Lai H, Fishman EK, Gerstenblith G, Moore R, Brinker JA, Keruly JC, Chen S, Detrick B, Lai S.

The incidence of subclinical CAD in HIV-infected African-American cocaine users with low CAD risk is high, especially in those with vitamin D deficiency.

Platelet COX-1-independent TxA2 generation in patients with acute coronary syndromes.

By: DeFilippis AP, Oloyede OS, Andrikopoulou E, Saenger AK, Palachuvattil JM, Fasoro YA, Guallar E, Blumenthal RS, Kickler TK, Jaffe AS, Gerstenblith G, Schulman SP, Rade JJ.

Aspirin's therapeutic action is via inhibition of platelet cyclooxygenase 1 (COX-1) thromboxane A2 (TxA2) production. The aim of this study was to evaluate TxA2 production, in the absence of platelet COX-1 activity, in coronary atherosclerotic heart disease patients with and without atherothrombotic myocardial infarction (MI). Differences in TxA2 production, in the absence of platelet COX-1 activity, between those with vs. without atherothrombotic MI were not observed when TxA2 generation was assessed on 11-dehydro-TxB2 production alone (polyclonal ELISA or LC-MS/MS), but differences were observed when TxA2 generation was assessed using 11-dehydro-TxB2 plus 11-dehydro-2,3-dinor-TxB2 (monoclonal ELISA). These findings highlight important differences between different commercially available assays for TxA2 generation and suggest that 11-dehydro-2,3-dinor-TxB2 may be critical to the biology of atherothrombosis.

Vitamin D deficiency is associated with coronary artery calcification in cardiovascularly asymptomatic African Americans with HIV infection.

By: Lai S, Fishman EK, Gerstenblith G, Brinker J, Tai H, Chen S, Li J, Tong W, Detrick B, Lai H.
These data suggest that, in order to reduce the risk for coronary artery disease in HIV-infected African-Americans, vitamin D levels should be closely monitored. These data also suggest that clinical trials should be conducted to examine whether vitamin D supplementations reduce the risk of CAD in this population.
