SLEEP-TIME BLOOD PRESSURE AS A THERAPEUTIC TARGET FOR CARDIOVASCULAR RISK REDUCTION
Ramon C. Hermida, Ph.D., Campus Universitario, Vigo, Pontevedra, Spain
Diagnosis of hypertension and clinical decisions regarding its treatment are typically based upon clinic blood pressure (BP) measurements, occasionally supplemented by wake-time patient self-assessment. Yet, correlation between BP level and target organ damage, cardiovascular disease (CVD) risk, and long-term prognosis is greater for ambulatory BP monitoring (ABPM) than daytime in-clinic measurements.

INNATE IMMUNITY AND HEART DISEASE
Anne A. Knowlton, M.D., University of California, Davis, CA, USA
The innate immune system is a primitive, rapid immune response that responds to detected threats by producing a rapid inflammatory response. A series of pattern recognition receptors (PRR) recognizes molecular patterns (pathogen associated molecular patterns or PAMPs) that are common to microbes and to danger signals (damage-associated molecular patterns or DAMPs) from injured cells.

METABOLIC SYNDROME CRITERIA: CAUSE VERSUS EFFECT OF CARDIOMETABOLIC DISEASE
T. Barry Levine, M.D., Drexel University College of Medicine, Philadelphia, PA, USA
Although metabolic syndrome (MetSyn)-criteria provide a convenient tool to recognize individuals at increased cardiometabolic disease-risk, they appear haphazard, mixing descriptors of body-phenotype with lab-tests and a vascular condition. Are MetSyn-criteria causes or effects? MORE» |

CARBON NANOTUBES SCAFFOLDS AS A NEW BASIS FOR CARDIAC TISSUE ENGINEERING
Carlin S. Long, M.D., University of Colorado Health Sciences Center, Denver Health Medical Center, Denver, CO, USA
In our previously published work we reported that MWCNTs used as growth supports for culturing neonatal rat ventricular myocytes (NRVM) increase myocyte proliferation and induce a more negative resting potential, suggesting that carbon nanotubes promote cardiomyocyte maturation. However, the mechanistic link between the enhanced cardiomyocyte proliferation and maturation and carbon nanotubes interaction was unknown. MORE» |
USE OF FRACTION FLOW RESERVE TO PREDICT CHANGES OVER TIME IN
MANAGEMENT OF SUPERFICIAL FEMORAL ARTERY
Amir S. Lotfi, M.D., Tufts University School of Medicine, Baystate Medical Center, Springfield, MA, USA
Background: Peripheral arterial disease (PAD) is a condition characterized by progressive narrowing of the arteries in the peripheral vascular bed which affect patient quality of life.

TRIGGERS OF ACUTE CARDIOVASCULAR EVENTS: CLINICAL IMPLICATIONS
Mohammad Madjid, M.D., Texas Heart Institute, Houston, TX, USA
Atherosclerotic cardiovascular events result from two separate phases of mechanistic processes. Whereas lipid accumulation and chronic latent inflammation lead to development of atherosclerotic plaques over a period of years, certain internal or external factors can “trigger” the transformation of stable plaques into unstable plaques within hours to weeks, causing an acute coronary syndrome (ACS).
