SummaryHeart failure is a heterogeneous syndrome in which an abnormality of cardiac function is responsible for the inability of the heart to pump blood at an output sufficient to meet the requirements of metabolizing tissues or to do so only at abnormally elevated diastolic pressures or volumes.
Heart failure may occur as a result of impaired myocardial contractility (systolic dysfunction, characterized as reduced left ventricular ejection fraction); increased ventricular stiffness or impaired myocardial relaxation (diastolic dysfunction, which often is associated with a preserved left ventricular ejection fraction).

SummaryThe goal of this paper is to evaluate the significance of the co-morbidity of nicotine abuse in adolescents afflicted with ADHD (Attention-Deficit Hyperactivity Disorder). Due to the nature of the disorder and its possible underlying pathophysiology of dopaminergic dysfunction, the use of nicotine can be implicated as a form of self-medication. I will provide evidence of the co-morbidity and early onset of nicotine dependence and prevalence of smoking habit in adolescents with ADHD. Furthermore, I will discuss prenatal exposure to nicotine and its behavioral consequences, followed by an analysis of the pharmacology of nicotine and proposed circuitry of ADHD. Nicotine use in ADHD adolescents can no longer be attributed to mainstream “peer pressure". There are reinforcing effects provided by nicotine that parallel stimulant medication used to treat the disorder.
