摘要:

&NA;This article reviews the chemical nature of cocaine, an increasingly abused stimulant. Following a description of the clinical manifestations of drug use, cardiovascular effects as well as routes of administration are described. Clinical complications of acute and chronic cocaine abuse include dysrhythmias, acute myocardial ischemia and infarction, sudden death, myocarditis, and cardiomyopathy. Clinical manifestations and assessment protocols are summarized. Treatment protocols remain focused on symptom presentation at this time, as there is no known antidote for cocaine toxicity or overdose.

摘要:

&NA;Stimulant abuse has grown in popularity, particularly since the advent of crack cocaine. Another commonly abused drug is methamphetamine (MAP) hydrochloride. Known as crank, crystal, ice, crystal meth, and speed, MAP can be produced easily from ephedrine, and it is widely available. This article describes the pharmacology, cardiovascular effects, and toxicology of MAP, as well as the management principles of MAP abuse.

摘要:

&NA;Anabolic steroids are synthetic derivatives of the hormone testosterone. Anabolic effects such as anticatabolism, increased skeletal muscle mass, and increased aggressiveness are usually desired; however, androgenic effects also result. Decreases in high‐density lipoprotein, increases in low‐density lipoprotein, changes in total serum cholesterol, hematocrit, and clotting factors, and the development of hypertensive diseases have all been implicated as resulting from anabolic steroid use. Research does not directly link anabolic steroids with cardiovascular diseases, but steroid use can significantly increase risk factors for atherosclerotic cardiovascular disease.

摘要:

&NA;Drug abuse causes a variety of cardiovascular complications that can be diagnosed with cardiac ultrasound imaging, including valvular disorders and ventricular dysfunction. The basic principles of cardiac ultrasound imaging, including fundamental engineering principles applicable to the health care environment, are described in this article. The basic modes of imaging‐two‐dimensional imaging. M‐mode. Doppler, and color Doppler—are discussed as are applications related to cardiac ultrasound: transesophageal echocardiography and peripheral vascular imaging. The article closes with examples of technologic developments expected to arrive in this decade.

摘要:

&NA;The Addiction Research Center at the National Institute on Drug Abuse is conducting a program of research focusing on both the acute and longer term effects of intravenous cocaine. This column reviews and critiques a pair of studies, conducted at the Center, that explore the direct biochemical effects of intravenous cocaine administration. Implications for nursing practice and research are discussed.

摘要:

&NA;Descriptive data were gathered from 15 families on which changes in the family were reported as a result of a myocardial infarction in one family member. Persons surviving their first myocardial infarction and their families were interviewed individually and simultaneously by one of five trained interviewers in each subject's home 6 months after myocardial infarction. Data were analyzed by reduction, display, and comparison of responses. Categories of changes that emerged from the data were those in family and social activities, emotions and personal life‐style habits.

摘要:

&NA;This study investigated whether patients who seek an explanation for their heart attack, as compared to those who do not, differ in their affect, in expectations about their future recovery, and in expectations about coping with their future. Forty‐two myocardial infarction patients were interviewed, in both the acute and convalescent stages, as to whether they had thought about “Why me?” Approximately half of the patients at each stage reported searching for an answer to that question. The patients remained generally consistent in their self‐reported anxiety, depression, and hostility over time; however, patients who had not thought about “Why me?” reported less anxiety than those who had. No significant differences were found in affect in patients who gave a specific cause for their heart attack and in those who could not. Patients were significantly less optimistic about their future recovery at follow‐up than when they were in the hospital, but there were no differences in expectations for future recovery or for future coping of those who had and those who had not thought about “Why me?”

摘要:

&NA;The effects of a relaxation technique (RT) on anxiety, vital signs, procedure length, and amount of diazepam given were examined in patients undergoing cardiac catheterization (CC). Forty patients were randomly assigned to an experimental (RT) or a control (no RT) group. No significant differences were found between groups in pre‐CC or post‐CC State‐Trait Anxiety Inventory (STAI) scores, vital signs, or procedure length. The experimental group received significantly less diazepam, and their STAI scores declined significantly.
