הלם שמקורו בלב (cardiogenic shock) (המ"ל) הוא תיסמונת קלינית, הנגרמת מירידה בתפוקת-הלב המערכתית בנוכחות נפח תוך-כלי תקין. כתוצאה מכך, נגרמות ירידה בזילוח רקמות והפרעה באספקת חמצן לרקמות. בסקירה זו נתייחס למאמרים העיקריים שפורסמו בנושא זה וננסה לגבש עמדה לגבי אפשרויות הטיפול בחולים אלה.

Diagnosis and Treatment of Heart Failure within the Communuity

Congestive heart failure causes substantial morbidity and mortality. Symptoms and physical findings can help in diagnosis, but have limited sensitivity and specificity. Objective measurement of ventricular function is essential in virtually all patients in whom heart failure is suspected; reversible causes of heart failure must be sought.

Out-patient management includes education and counseling, emphasis on and assessment of compliance with diet, and pharmacological treatment. Angiotensin-converting enzyme inhibitors are the mainstay of treatment but are underused, and maximal doses are not given, apparently because of concern about side-effects. Diuretics should be administered only as needed to manage fluid overload. Calcium channel blockers are relatively contraindicated in patients with impaired ventricular function. Patient follow-up should be guided by results of the medical history and physical examination. Routine serial testing of ventricular function and exercise performance is discouraged.

Emergency Stenting for Acute Left Main Coronary Artery Closure during Cardiac Catheterization

Alberto Hendler, Oren Agranat

Catheterization Laboratory, Rama Marpeh Hospital, Petah Tikva

We report a case of acute closure of the left main coronary artery, a rare complication of diagnostic cardiac catheterization, treated by emergency stenting prior to aorto-coronary by-pass surgery. We suggest encroachment of the Judkins catheter into a calcified left main ostium, with dissection and acute thrombosis of this segment, as the possible mechanism.

Clinically, the patient's condition deteriorated to cardiogenic shock and loss of consciousness. Remarkably, there was no angiographic evidence of significant left main coronary artery disease, besides the presence of calcification in the proximal part of the left coronary system and ventricularization of coronary pressure at the time of engagement. We chose to slide quickly the angioplasty guidewire through the left main coronary artery, which allowed prompt mechanical recanalization and rapid restoration of coronary flow, with dramatic clinical and hemodynamic improvement. This relatively simple procedure allowed stenting the left main artery after brief predilation, and the patient came to by-pass surgery in excellent condition. The rationale for surgery in this case was the need for complete coronary revascularization because of significant 3-vessel coronary artery disease.
